Any All Pro head results yet?
Any All Pro head results yet? Any All Pro head results yet? Alot of people were talking about switching over to the All Pro heads, any ETs or dyno results yet?
Thanks, Shawn

Other than the fact that one of the fastest lsx cars right now is using them I haven't seen any. It would be interesting to know. These are fairly new and I believe are made mostly for boost applications. Thicker deck and more material around the bolt holes.
I have sold two sets that are running on cars now. They are both turbo cars although i'm sure the heads would shine in a NA application. My plan called for some back to back testing after getting a good 1/4 run with my reworked AFR's but my trans keeps fighting me. I think the trans problems are cured, but been so busy lately its hard to get to track. I should have some dyno data on the All Pro with a turbo before the year is over.

Those sound interesting..
I'm doing a 327 (ok 329) turbo project.. Trying to make a true street powerhouse... If I could afford a sleeved block it would be a short stroke 349.
The MPG off the boost will be better than a stroker. The engine will be less knock prone at a given boost level. ETC. there are pros and cons to everything...
The plan is to get the best MPG (really miles per dollar) and best performance combination from local pump fuel.... We have alot of E85 available locally and with rising gas prices it is less than 87 octane price wise but alot higher in octane.. Just get larger injectors and tune for it.. Then My 1/4 mile track fuel will be E98..
I have done it on an import and alcohol + turbo = happy combo..

I have not used the All-Pro heads as of yet, but I do know that they (Callies and All-Pro) are doing some things to improve the design. Callies will have a booth at the
N.vs S. shootout with some of the new design heads on display, or that is the plan last I was told.
I understand that Cartek uses them on their 427ci setups, maybe they have some input?

All Pro sells two heads, they have their regular ls_ heads that can be purchased unported or ported. They are also in the process of debuting a raised runner head that will have huge flow numbers but require custom intake solutions.
As far as I know, two sponsors on our site who carry All Pro are W2W and Callies.
The first generation LS_ All Pro heads had huge exhaust flow numbers, they have revised them a bit. Anyone have a set of the first gen heads that they might want to get rid of?

Very true. The raised runner design has always been a interest of mine. Fill the bottom of the port with epoxy and you have a better shape in the intake. It makes since.
The intake no longer works and something has to be done for that. TEA has done a few sets and made the 90mm intake from fast work with the raised runner design.
It can add some nice flow numbers.
When All pro finishes these heads I wonder what they will cost. This could be a nice addition but if they are 400-500 dollars more then what they offer now then their sales wont pick up very much from the new design. With AFR and ET performance around a 3000+ dollar head wont sell well IMO even if it flows 345intake and 260 exhaust.
I have a set done by Larry Meaux waiting to go on my 427 and the #'s look promising. Been swamped at work, hopefully I'll have the new setup fired up in 4 or 5 weeks and I'll get some #'s. My car is setup for the bottle mainly but still runs decent N/A. Hoping to make around 550rwhp thru a th400 and a 9'', who knows we'll see.
Looks like I'm gonna be one of the guinea pigs again
I would of thought there would of been more of these heads being used by now, guess not.
