Anyone have flow numbers on their AllPro heads?
I'm curious to see if anyone has flow numbers for a set of either their ready-to-go heads or the unported ones that they subsequently had someone else finish up. I'm trying to figure out my fall game plan with my car.

PSJ I would really stress looking into the ET performance 265cc head for your combo.
Cost is less, THEY ARE A SPONSOR, they come complete, and all around are a fine head. The All Pros suck out of the box, I flowed a set stock but the negative to my findings is you have to set the heads up yourself. I believe off hand they were 289-291@600. I will have to pull out the old flow sheet.
Cost was A LOT after buying my own parts.
The ET heads on paper whip the All pros like a Vette whips a escort.
Look into them and give back to a sponsor.

I'm finishing up a set of All Pro heads this week. I'll post some results when the heads are finished. I tested the heads with 2.02"/1.57" and 2.08"/1.60" valve setups. Intake port flow for out of the box heads are ok, but considering the rather large (235cc) runner volume they could do a bit better.

I would go with 11-degree heads over 15 any day. Call ETP.
I think the ALLPRO's were really meant to be a race head, and never really intended to be run out of the box. They have a super thick deck and options on rocker pedistals and height (around the valvecover edge). Really a custom head that "can" be used out of the box.

Are ET Heads new castings? My ported 6.0's are pretty average, almost mediocre. I'd like to see what of of excellent cylinder heads would do with my boosted setup.

I would love to do you a set of heads, maybe I should finish my AFR castings and send them to you to try. No....wait a minute.....don't I have a set of killer LS6 heads that I sent to a guy in Chicago that I never got paid for? Well, I guess I can't do that then, its the bad apples that ruin the bunch. Better yet, if I do send you a killer set of heads to "try", can you get my other set back?

Our casting is our own, not anyone elses. I agree with Brian, if it hooks it should be in the 8's.
Yes the 265's do require a custom rocker, but if you are already planning on buying a set of Jesels the price become voided becasue you are already going to spend the money. The 255's will not require a Jesel rocker only, you can use the factory with our custom stand.
Here is a picture of the LS7 and the 265 head.
P.S. Sorry, not trying to highjack the tread.

My AllPro's flowed 340cfm at .625 on a 4.0" bore. I should get the sheet one of these days, maybe tomorrow when I go by the shop.
I only looked for the .625 lift since I was using a .630 lift cam.
My heads have 2.08 intake 1.60 exh and uses REV valves. Hand ported.
I know another set flowed 356 at .625 on a 4.125 bore.
Here are some pics of mine:
If I get the sheet tomorrow, I'll post up all the numbers.

So the ET 255's are what chamber size? Are they a reworked AFR? 255's available in like a 70-72cc chamber? Link to flow numbers?
I'm not fixated on All Pro heads, but I'm more interested in an aftermarket casting. I'm not looking to go to Jesels anytime soon since I don't really have the time to mess with valvetrain geometry stuff right now.
My ported 6.0's were done by Diamond Racing, 299/219 at 600.

Our cylinder heads come from 72cc all the way down to 35cc and are available in 3.900,4.00 and 4.100 bore sizes. These are NOT a reworked AFR casting at all. Our casting is completely different from all others out there. The 255 head is in process but is not released as of yet, it may be a few. Send me a e-mail at Craig@etheads.com, I'll send you over my half finished catalog but it does have the flow numbers and other information.

I still don't see the need for heads on your setup, I would think getting the thing to launch and down the track would be better money spent getting another 3/4 a sec out of your car. Heads aren't going to do a huge amount on a blower car. I'd go talk to Billingsley instead.
Craig, Do the Jesel rockers require any shimming to get them to a set height with your standard valves? I would imagine the whole setup would bolt right in without too much work since it was designed specifically for your castings.
