- Woah. We're on RUclips!
Today we begin the process of turning our 40-year-old NOS Stage 3 CJ Batten Oldsmobile Heads into something bad to the bone. In this multi-part series, we are going to turn these BARE cylinder heads into a fully optioned out, race ready set of heads for our small block race engine. Tag along as I walk you through my process as we start to CNC port these cylinder heads in the Haas UMC-750P.
Let's GO!

34 year old Olds enthusiast here, love seeing the old stuff come back to life. Real Olds Power.
I had to come back and watch this a second time... can't wait for the next video!
Just another OLDS guy here,engine machinist,engine builder, fabricator and welder. Like to see other people doing things outside the box. Keep them coming!
Just what I’ve been looking for! An OLDS guy doing OLDS things. Keep ‘em’ coming ! 👍🏼👍🏼
I’m 54 been a blacksmith for last 30yrs just bought a mill n lathe-never stop learning
Good Video... Keep it up! I'd like to see this project progress to completion ... Thanks for taking the time to make this video.
Don't worry, we intend to debut this engine in the spring. I had better get the ball rolling and finish them out!
Best video I've seen in days. Bravo! Fantastic
Great first RUclips video
I'm OLD's fan! I built a 350 old's that put out around 450+ HP back in the day. I have a 455 in the works now. The engine is out of a 1970's cop car but what is cool it says Oldsmobile highway patrol on the air filter lid!
You are doing great so far! This kind of content is right in my wheelhouse.
So much hotness! I want a sick intro, good video home slice.
Intro is the only professional thing in the video 😁
Very cool video
Keep'em coming. So far so really good 👍👍👍
Good video Thanks for posting it these are a piece of Oldsmobile history keep put up videos
Big RUclips guy 🥳
Do videos play upside down in Aussie land? 😉
Thanks for the detailed info ! Great video!
very good work!!
I may not be a gearhead, but old, untouched, art pieces are really cool things..... be it a certain pair of vintage mountain bike forks, a 35yo balsa rc plane kit, or a pair of Vfet transistors.
There's nothing better than playing with unobtainium!
Well done young man.
Thanks for sharing.
Great video.
I like seeing you use the Haas Mill.
Very impressive. 👍
I just subscribed to your channel.
Have a great day.
Thanks for the video. Could you make a video of the process of race porting Pontiac iron d-ports to flow 280+ cfm ??? I see a pair of those heads on the bench behind you throughout the video.
I could watch that thing cut an intake port all day. Nice job. 30 years of mostly Chevy NA engines, i never took a good look at the Olds. Looks like they took a big blocks bad cylinder intake ports and threw em on the small block valve layout with the 2 middle exhaust valves together. Olds took the worst attributes from both of them and threw em together. 4 head bolts per cylinder and a weak rocker stand area. These motors seem to be challenging beyond most. Sayin all that, its still twice as cool as seeing another LS. Keep on talkin to the camera and sharin info and ill keep a watch
Good stuff!
Great job brother. Keep it up.
Interesting and good content Thanks
350 old diesel performance that would be the crazy stuff! Lol
I remember a set of these in a speed shop in Troy New York 40 years ago
If only my old man still had his battens!
can you show us how you come up with the CNC programing
Hey Peyton, great video and info. Been following your journey and have become a fan. At some point I think I will pull the trigger and purchase a set of your heads for the 455 Olds. I have a question about iron heads. Do you have a cnc program for them and do you offer that machining service. My other question is if you have the cnc program for irons heads does it pocket port below intake valve seat and open the throat to an 89% ratio. This seems kind of tricky for a home porter to achieve in itself let alone worry about breaking thru to a water jacket.
Great first video you’ve gained a subscriber I,ve got a set of these heads they have been used though they are going on a former nascar engine
Have you done anything for port mapping the 90's LT-1 cylinder heads?
There's a story behind this particular pair of Battens. ( singular for a while ) This story is coming as to how these came to be a mated pair 😁😁
That's what I thought, if it took 11 years I assume that means at least 10 from the purchase of one to the other.
Id like to hear some background, pretty knowledgeable for a 25yr old young man. Interested in the 11-12yr story as that would equate to around 14yrs old. As the owner was this a family handed down business. Sorry for the inquisition, but i find it interesting. Props man you have great presence in front of the camera.
PDD was started by myself 3 years ago as a side business!
I’ll be highlighting the story behind these heads, and how they came to be a pair in the next video.
It not rocket science with cad cam any body can machine ,I'm a manual machinist for 35 year & can run cnc so you just have to the will & big pockets $$$ ,if someone train you 1 1/2 to 2 years you can do what this young man is doing now that's just to be a Operator ,set up man & cad cam 3 too 5 years
@@jackwillson8099 Was your reply to me? I never said I was impressed with this young man because he can do machine work, I've got many friends in manual and cnc and I hate to say it but they're not the brightest of beings. I do think this young man of 25 has got an impressive start in life with this buisness and not many guys have churned out they're own set of billet heads at such a young age and oldsmobile at that. Not many a grown man knows about Batten or have any idea the influence oldsmobile had with performance other than the muscle car era. If this head story goes back 11 to 12 years ago and includes this young man at the time then he was only, what? 13 or 14 yrs old. I can't say what I was doing as a young teen of 13 or 14 but I didn't get drawn into muscle cars/horsepower until I was atleast 16.
This stuff baffles me, I have no idea of the process you folks have to do to take something like this and program that magic box to shape those ports, cnc porting is pretty wild. On a mass produced/cnc ported head I can wrap my head around it but a custom head it baffles me. Maybe it's !not as crazy as I think but I don't think so. Regardless that's some talent and I can say you did a beautiful job those ports are pretty sexy looking. I'm envious of the talent and resources machinists have when it comes to high performance engine parts, machining is the most expensive, complex and most effective part of making big ponies. I'd love to be able to buy a bare head and chuck it up load a program n hog it out to exactly what I want it to be. Have some skill and buy a CNC mill and look at how many new best buddy's you get lol.
Any time someone breathes new life into 40+ year old parts. Well you have my respect and admiration! What's going on with the ole D port Pontiac heads? hehehe
Check Kauffman racing, I sold a pair of aluminum hi port heads , mine were 365 cfm and u could buy 400cfm, they sell a wedge head that flows more and a canted and hemisphere head that flow around 520. I was listening to Daren Morgan the other day and he mentioned how Harley heads in Rostock flow over 700 cfm
Can you run Chrysler shaft style rockers on those heads to spread the load across the entire head?
These will be set up with T&D shaft mount rockers
That exhaust would be great to spray nitrous.
I’m from Lansing…home of Oldsmobile!!!
What olds engine block(s) can these heads bolt on?
Whats the bore spacing and min and max bore the heads will work on?
Oldsmobile only had 1 bore spacing in the 350-455 blocks, and that is 4.625. These heads will fit any bore for the most part that would fit in those blocks.
So that being said, these fit any and all small or big blocks that fall under the years those engines were produced.
What short Block you plan on running them on?
30 over 455 with stoker crank, hydraulic roller?
@@flyonbyya this is going on a 431” “D” based small block.
Solid roller with ≈ .750” lift, super tricked out billet Moldex crank(1.889 Rod Journal), billet CP-Carillo rods, Custom Ross Pistons, Mechanical Fuel Injection, etc etc.
This is a pretty nice race engine for the bracket dragster. Nothing over the top, but it will be stout for what it is. This engine is a culmination of parts that have been sitting on the shelf as “spares”.
@@PerformanceDrivenDesign
In 1985, I dropped in a bone stock “C” headed 68 455 olds in a 71 2 door Skylark…
Fun
Fuuuun
FUUUUUN!!!
Will you flow these heads once done? It's nice of you protecting your cap with these protection glasses when cleaning your part with compressed air. ;) Great video!👍
Safety squints, engaged!
@@PerformanceDrivenDesign Did you flow these heads before porting them and will you flow them after?
@@dyoutubechannel8218 I did not flow these heads before porting them, because in my opinion, they were never meant to be ran as cast. I don't care about the overall gain with these, but rather where I am going to end up. This is far from our first set of these heads, hence why I did not have to hand develop a port to digitize from the start. We know their limitations and where the port should end up at, but I wanted to try CNC'ing them just for kicks.
We will be flowing these once the new valves and seats are installed. This is the first set of these we will have put 5/16" valves in.
@@PerformanceDrivenDesign Fair enough, thanks for the answer.
For all the Dremel tools I wore out doing this by hand, decades ago, could have bought a CNC😅
Heads look good brother...any combustion chamber mods on deck? What do you think of Vizard's stuff?
Vizard is a very talented, and very knowledgeable individual.
However, no combustion mods on these heads. Battens are very prone to cracking after being welded on, if done improperly. While we’ve repaired and altered many cylinder heads over the years, it’s not worth the few horsepower I might gain to go through the effort to weld the chambers up and reshape into a traditional fast burn.
@PerformanceDrivenDesign awesome and fair enough, the best horsepower is reliable horsepower! I'm doing an Iraqi Taxi build (these were Canada only) adding a turbo and doing Vizard's old school Chevy combustion chamber mods to it...I'm filming the whole thing too but haven't released any footage yet. Rock on with the videos brother!
Lol battens dinosaur heads lol i haven't seen a set in 30 years lol
If your nose runs and your feet smell there was an assembly issue during production😊
What did they flow cfm & port velocity number @ .550 lift
These have not been flown yet.
Why .550? That’s a little low for what we’re doing 😉
@PerformanceDrivenDesign what lift you running .800 lift lol see when I was building them 455 or 400 iskdaern had a 320 magnum that was the set up for street,and there were no roller cam for oldsmobile 40 years ago . 575. 550 is more then enough either 30 degree valve job it will out flow any 45 valve job at low lift !
@@jackwillson8099 Yes, I will be very close to .800" lift in this engine. With our current head R&D, we have determined a 50-degree seat cut is our best approach for this platform. With the larger throat that gives, coupled with the port CSA, it should be a very nice performing port for the engine size and desired RPM range.
@PerformanceDrivenDesign well you have the technology now Jessel valve train, spin. Tron & camshaft, valvesprings software you. Guys have it made it almost Idiot proved not to build a higher horsepower motor with all the new technology lol
Rocket racing no longer making heads?
Ever looked at a wise cylinder head? there arent many out there, but as far as i was aware they're still the newest design head for the olds
Feel free to go check us out on Facebook or Instagram, and you'll see the newest and baddest billet Oldsmobile head to have hit the market.
We also offer CNC programs for the newest Edelbrock castings, which should rival the performance the Batten heads have given.
What system do you use for scanning and then designing your porting?
We use a Creaform3D HandySCAN 700 Elite, followed by importing into Solidworks where I then use a GeoMagic add-in to help me manipulate the mesh to produce my port and chamber surfaces.
As you’ve got these modeled, is there a possibility of a billet version, in the future?
We’ve designed an in-line valve billet head that puts these to shame. 2 sets have already been machined, and one is nearing its time for dyno testing.
@@PerformanceDrivenDesign That’d make for a kewl episode…
Just subbed!🫵
Turn on RUclips three days and already has an intro😮
If it’s worth doing, we do it right.
I am surprised that you do not 3-d map the bare head so you could actually reproduce the entire head.
This head is not worth reproduction. We have a very powerful 3D Laser Scanner that we will showcase later on in the channel.
I’ve produced a billet head that makes this one shameful, so it made no sense to me to take a step backwards.
But are there any good h/p blocks to bolt them to?
Why there aluminum made in real aluminum . Meaning they tig up like no other then billet and you cant ruin them only loose alot of time behind a welder
Exactly why not these youger generations dont know what Oldsmobile and pontiac mean when you think of torque you should see it just like this "TORQUE"! "
GREAT VIDEO! Keep it up!
