Same although I assume not much would be gained till top end is hit and most the benefits would be from the upgraded valves and reliability from proper size and none damaged valves. Wish I had the tools and or someone in the area who could touch up my engine but the 6g75 isn't really a well supported engine.

decades ago my boss made one of the most power vw engines, one thing he had was a massive lift cam , and he machined the pistons to compensate. he was a mechanical engineer.
Dont knock those 1200lb beetles. They dont take much power to make them pretty quick as well as the weight distribution really helps with traction when the powertrain is basically right over the drive wheels, pretty much the perfect drag car setup really.
Would be interested in knowing more ! Including an opportunity to speak with him about it ! One thing I am, is a VW PERFORMANCE nut ! Anything you could do, to give me the opportunity to speak with him, I would genuinely appreciate it !
I take VWs seriously. My first new car was a MKIV Jetta 1.8T. I love the sounds and feels that German cars have, and a VW was the only way I could afford one. I once worked on a microbus, and it amazed me that a car could be that simple.
I have been watching ur short Videos and now I am a Subscriber here. What Breath of Fresh air to see this type of work is still being done. I am Retired myself but again this is really a “Dying” Trade. Grant you some ppl think there is a Dime a dozen shops around that still do this but not a GOOD as ur shop. Most Machine shops today want Quantity instead of quality, You have chosen Quality. Great Job.
I wish the machine shop I've used in the past would let me shadow them while they machine my block and heads... I would likely get in their way and annoy them when they want to just work... but would be awesome to see the work done. Thank you for filming and putting your content up! I can't get enough of this!!! I've always "known" what they do at the machine shops with my heads and blocks, but could not understand how they get a lot of those items done... Now I know how! You do amazing work and turns out looking GREAT! Lots of math and experience goes into this work. I've worked in construction and other mechanic work my entire life and I know there are those things where when trying to tell someone how tight or how to do something, you say, just feel for it to be right... There has got to be some of those scenarios with your setup where you get it lined up and ready and you just know how far the grinder "wants" to go and you really can't explain it, but just feel and know it from experience.
Just wanted to add some Apples to Oranges discussion to the mix. I've done a lot of seat profile testing on the 7.3 IDI, including the BSS cutters you used, and they weren't effective at all (On the flow bench) The IDI has a completely different intake port and larger valve, I assume that's the reason for the difference. I'm still working on the exhaust side of things. Also, the pocket clearancing didn't make any difference... Again, just so I don't get yelled at, I'm talking about the IDI, not the power stroke here. These mods might very well make a difference on the PSD (I haven't tested them) I just didn't want people to assume they will on an IDI.
30 deg seat angle is favorable to low lift flow while 45,50,55 for your mid to high to the xtreames of pro stock. Every single port design will favor completely different seat angle. 5 angle isn't the end all be all and especially when you consider stock seat angles of every 15 deg. Every detail matters and changes things. Port design, port angle to the valve, port angle to the cylinder, valve angle to the cylinder, 2v,3v,4v,5v,valve head dia/bore, lift, lift/dia valve, curtain area, tumble, swirl, local port velocities, air velocities around the valve, port shape as in circular being most efficient, oval next and square or rectangular least, the circle having less surface area thus less frictional losses. Thats just some of it.
@@_FJB_ the biggest gains I've seen so far on an IDI head (again apples to oranges), on the intake, even more than doing any porting whatsoever, is widening the seat to .280" at 30*. This bumps overall flow 7-15cfm across the board from .100-.500. I havent gotten too deep into the exhaust side yet, but intend to do some exploring there. Every head is different, and IH did a pretty good job in stock form with the 6.9/7.3 IDI.
I paid over $1300 to have my heads completely done at a shop called Klispies. I gave them a few good cores to chose from and preferred having them built vs buying "reman" heads.
I met Joe Mondelo when I went to school @ NTC Bemidji. He was the one that recommended me to the school when I was searching out schools over the phone.
if / when i ever get around to my dream engine build of a 6.7L cummins with a P-pump, id love for you guys to do the machining on it. your attention to detail is awesome and i see that you actually care about your work. im a machinist as well but have never done engine machining work, ive always sent it out because of the special equipment needed... i hope that one day ill have some work for you... but untill then, ill continue watching your awesome videos! cant wait for the next one. BTW, i really like the high performance builds, they are fun to watch :)
Do you refer to one big master book with every engine spec known to man or do you have an engine specs book for each car maker? Are they available to the public?
Question on cutting the relief. Doesn't that create a hot spot where the two reliefs Siamese into each other? I would think you'd want a fillet in that area to reduce the chances of that.
I too would like to know about this. I know that 7.3 heads can crack in that space between the valves in stock form, does the sharp peak make for too much of a stress riser?
I noticed that your valve seat driver tool has a mushroomed head from lots of productive use, and I'm concerned that a bit of that driver head could spall off next time you whack it hard and injure you or the cleaning guy (or anyone else standing nearby). Maybe run it by a grinder and eliminate that mushroomed head? I want to keep you guys healthy so you can keep making more videos for me to watch!
Curious if you guys have ever done a mild port job maybe just to clean up factory casting. Would it moderately improve flow? Looking for a simple way for a stage 1.5 ish build to breath a little easier for efficiency purposes.
I have a few extra set of 7.3 L heads, I was wondering what it would cost to have you go through a set as you did in this video. I will be running around 6-650 hp and already have stage 2 valve springs, retainers and shims.......thank you
You guys do phenomenal work. I'm not sure how your pricing is, but I'm sure it competitive, especially considering the amount of shops that do what they did to his first heads.
I’m a little surprised considering I’ve been running a stock bottom end stock head with a set of cheap aftermarket valve springs for 8 years would definitely be interested in all the part number for the valves and tooling for my future billet rod engine
Need any advice, and input as possible ! 7.3 was the best of the bunch in my opinion ! But I know there is a lot left on the table ! I am paralyzed from my neck down, and looking for any performance advice I can get for daily work, daily driven F250's and a F350 in our fleet !
To start with....cold air intake, and 4" turbo-back exhaust. You can get a PHP Hydra chip to increase performance. Next would be turbo, injectors, fuel increase, etc. How much do you wanna spend cause a lot of hp equals big $(like over 450-500 hp is when it starts getting expensive)
@quadsman11 - there’s a lot left in a seven3 PSD, enough to do a decent day of work. Fuel and air are the main upgrades - you can use your OEM turbo and upgrade the compressor side with a larger housing and compressor wheel. Hybrid injectors - no need to upgrade the oil side ( hpop) if you go with 238cc/80% larger injectors Those are single shot and if you use the Hydra programable chip in your pcm you can run whatever tuner of choice - a single shot tune from Brian @ Jelibuilt will do the trick. Larger single shot inj was my best performance upgrade of choice - there are only some 60 horse left of fuel in the OEM split shot injectors that came with the truck - some 300 RWH at best. 238cc/80 % nozzles will with correct supporting mods give you from 460 RWH - 520 RWH I have been running two Excursions now for the last 10 years. Performance are greate even fuel consumption are within acceptable range - 18-19 mpg highway with ton of pulling power. Those engines are old and often worn and having a hired steering wheel holder that does not care with that amount of power can and will brake stuff. Lock the Hydra on a low setting and remove it. Remember to change the engine oil att 5000 miles according to spec as the HEUI injection system are brutal to the engine oil. Theee are tons of mods to do on these engines if you like - a good place to find and discuss such I have found to be Ford forums. Ford Truck Enthusiastd DOT com is one of the better with hardly any banter and brawl. All the best , Helge 🤠🇳🇴

You should provide an update when the truck hits the dyno to show what effect all the extra machining had for the engine.
Same although I assume not much would be gained till top end is hit and most the benefits would be from the upgraded valves and reliability from proper size and none damaged valves.

Jib well done. Machinists are just not appreciated enough. Without you guys us wrench turners can only get so far.
I'm definitely sending my 7.3 heads to yall.
I have had 7.3 Fords since they came out and have never had head or valve issues.
Edit- lol I’m not pushing 550 horse either. Makes sense now.
I’d like to see the flow numbers with that low lift mod done. I bet it’s crazy better.
It would be very cool to see before/after dyno/customer impression for this.

awesome work
What a cracking video, shows you how much work that goes into a valve job.

Not only would this relief tool help diesel heads, it would probably be great for the Chevy 348/409. It might also be good for the VW VR6 12V.

Play it now!
its nice to see you are getting onto the performance area. Are you planning on measuring the CC combustion chambers?
Not really much point, there is very little chamber volume left in those heads - they're as flush to the head surface as you're going to get.
awesome video. I love my 7.3, i actually miss driving it since i parked it for a new bed and rust repair about 2 years ago
For the love of spawl, grind off the mushroom on that seat driver. 😂

Haven’t watched in a while. But this is a great video
If it was .020” below minimum thickness spec, will there be issues with pushrods? Or will the lifters soak that up?
Thanks again great stuff
What valve springs are you using on these heads? I run 930 springs and turn 5300 rpm with no piston to valve contact.
