Hard to beat an Old School Machinist Allan. I use the same Sioux Valve and seat grinder also. I totally agree with Bill on the seat grinding. Good video. Have a great day. Take care, Ed.
Thanks Ed. Old school machinists are a treasure and getting harder to find. i am lucky to have Bill available. We will do more videos with him, by popular demand. AG
Thx so Much for introducing us to Bill....Amazing cylinder head Results from Basic reliable tools & equipment run by a Skilled & experienced Specialist who takes the Time to do the critical job Correctly !!! ......Probably 1 of the most Informative video you've presented & really Appreciate you Sharing.....Very interested in the "Pito Tube" there....Maybe you could ask Bill about the Usefulness of the "P-D Valve" (Pressure Differential drilled test Valve) for accurate Precision Repeatable air flow measurment Precisely at the valve seating Face at any valve Lift or Radial point ?? ....Big Thx again for your time filming & Sharing this !!
Hi Tom, I've been racing and busy I would love to buy one of those valve it would help to figure out what goes on past the valve, alot happens in the chamber that's hard to explain.
Fantastic video! Allen I want to wish you a very Happy Birthday tomorrow! This reminds me so much of my late brother. He has the very same Sioux seat grinding set up as Bill. He always ground his own seats with a stone, as he always said they were superior to a cutter. He spent so much time on our racing engines grinding seats and getting the runout as close to zero as possible. You can hear the difference in an engine that is sealed up well when you do your own seats, valves, and get your ring end gaps perfect. They really run crisp and give you the edge in making horsepower as well. Bill's knowledge and experience is absolutely top notch! Thank you so much Allen for this video! It really made my day!
In the early 60s when Colin Chapman brought his Lotus cars to the Indianapolis 500 one of his innovations was the refueling rig. There outlet pipe was limited to 1.5 inches iirc to limit the fuel flow for safety. To the surprise of the other teams the Lotus refueling rig had a higher flow rate even though the outlet pipe was the specified diameter. The difference was that Chapman had put a proper bellmouth on the inlet end of the 1.5” pipe inside the rig’s tank. This dramatically increased the flow rate leading of course to quicker pit stops. The same idea is applicable to all fluid flow plumbing ( earth’s atmosphere being a fluid). Wherever the fluid path enters or exits a smaller diameter passage a proper bellmouth will give the highest flow. Hence multi angle and radius valve seats. It also applies to oil flow, fuel flow, etc.
Wonderful content gents. I’m a 43 year old union electrician in Los Angeles, been into engines for a few years, my late pops sparked my interest having a 1979 Ford Mustang 2 Cobra, a 1964 El Camino with a 396 taken to 420, manual/posi drag car, my only build to date is a 10.2:1 SBF 331 w/ 190 cc blueprint cylinder heads, Scat Rotating Ass., Forged Mahle flat tops, weiand street warrior dual plane, 600 vac sec carb, 1-5/8 mid length headers, running through a top loader 4 speed in my 1980 4x4 Bronco, cam is comp xe266hr12, pretty happy with my mid range pump gas runner. Not a drag car but fun to bang gears. Plus it’s unstoppable in snow (live in mountains at 5200’ elevation) had i the opportunity to redo, I woulda gone 408 - 351 stroker, or 427 clevor, so I’ll be watching and learning until then. Keep up great content fellas
Thanks for your comments Piercer. Sounds like you built a nice piece, but you are correct, bigger is better. Easy to make great torque on the street without high RPM. AG
AG, I had the same setup as Bill has... I always use stones for the different valve angles. Never had or used cutters. My friend has kit that puts all the angles at one time by hand... For race engines... I put 5 different be angles on a small block Chevy. You don't or cannot put that many angles on a big block Chevy head because it is designed different. I took a set of 781 castings, closed chamber oval port heads and put bigger valves in it. 2.19 intake and 1.88 exhaust. Had the heads cut for the bigger valves and than I finished them and cleaned the ports up, bowl blended. Turned out a good set of heads, also has to cut the top of the guides down to where the retainer would not bottom out on the top of cam for the lift on the cam and cut the guide for seals also. and the valve spring seat bigger for some roller cam springs. 1.550". Thanks AG...
That was a great video. I will be following along. Thanks, guys, for taking the time for us fellow gearheads. I would love some more stock eliminator and super stock stuff. It's is amazing how those guys get stock engines to run.
This is good stuff!!! This is exactly what I would like to see! I bought a souix valve grinder & a old souix seat grinder. And a set of new stones. So far I've dun two sets of ford FE heads & they seem to be working well, but really, I have so many questions! I'm self teaching on this stuff! I read about & try to research as much as I can & if I run into someone that I feel I can ask questions too, I try to ask & talk with them, but there is so much & I have so many questions, I can only impose on these guys so much. This is just for me & my hobby, these guys are trying to run a business! They have already helped me so much, I feel it's out of bounds for me to bother them to much. So ya, more of Bill & working with stones!!!
Thanks Jesse for your comments. I have discussed this with Bill and he has agreed to help me respond to questions or comments on my channel. Please feel free to post your questions and Bill will reply. I am sure many people will learn from this, there are no dumb questions. AG
Happy Birthday Al and congrats on reaching 5k subscribers!! Love your channel. I’m a newbie and I’m counting on your channel and others like yours to help guide me through my first build. Thanks for sharing so much of your knowledge.
Thanks Conservator. I was wondering how long before someone caught that. I was just on the way home from playing golf. Bills shop is close to the golf course, about a half hour from my shop. AG
@@goldsgarage8236I want to add that I really love how you go into the nitty gritty details. Not manny do so. 👍 I’m looking forward to the next video and watch Bill explain more about flow!
At 04:02 That Gross example of an Original valve Seat would have to be "Tilted" > 0.060" to accomplish that far out of seat to guide Concentricity !!! ......I have "Heard " that some aluminum Head Manufacturers, in order to save Production time & Money simply hammer "Pre-Finished " seat Rings into the seat pocket Without measuring any Reference to valve guide Centerline or Anything else !!! ......If true,....Aside shear Luck, there's No way to maintain a reasonably decent 0.002" Production run of finished product.......I watched a Well known Ca located performance cylinder head manufacturer "######### Cylinder Head Assembly Tour 2011" & although I may have Missed it, saw No footage of Any valve seat Machining or measuring Runout After the seat Ring was Pounded in.......
@@tomstrum6259 I needed a couple of guides for a BBC engine, I knocked a couple out of a broken casting and thought I would cut them in, I was mistaken. There was no way I was going to cut them that much, so yeah that can't work well, but, they may do that.
How are you brother? I love your channel sir. You give alot of really good info. I have a question for you. I am working on my first swap. Not first engine tho lol. Ls3/4L80E in a 03' Crown Vic Police Interceptor as I have told you before. I hit my hands on a 6.2l block and a set if bare low mileage 821 corvette/camaro heads. For a street/ maybe an occasional track car. Mostly burn outs and ice cream with the wife and grand kids. What do you think of the stock hollow stem intake vales? Or would you go stainless steel valves? I am bit sure which way to go with the valves. N/A build. 4 to 450ish wheel somewhere in there. Ish. I am not looking to be the next Street Outlaw. Just want a reliable fun burnouts and ice cream with the family without dropping 10 grand lol. Thank you sir.
Thanks for your nice comments and the question Hugh. I have asked Bill Little to reply to your question as he has more expertise in this area than i do. Please watch for Bills response. AG

Grinding an Indexing Notch on the Pilot is Really cool !! Lots of learning Here....Thx AG for taping into all this Knowledge !!

Thanks for you comment as always Jim.
Lot's of information that I've heard of but never explained . Will be watching the next video and learning more . Great video .
Thanks 25vrd48. We are learning together. Lucky to have Bill to teach us. AG
Thank you for the field trip it was very informative
Thanks STP. I will be making more videos wit Bill. Look for them. AG
Very cool to see the valve work being done and you explaining the benefits! Thanks

Please increase your recording volume. It is easy to turn it down but listening on a smart phone only has limited olume.
I apologize Dale, I had my microphone turned off for the first part of the video only. Hope the rest is ok. AG
A stone cuts all the way around and leaves a smoother finish ( no jittering). people don't use stones because of the time it takes. My opinion.
Setting the depth would be a concern for me.
Precisely Equalize all the Seat Depths with a multi- Cutter & then "Kiss" the Seats with the appropriate finishing Stone ???
