The only numbers that impress me are the flow numbers. When a set of heads cost as much as some complete short blocks, that's just insane, but to each is own.

I'll stick with my AS heads.....

Good job on getting those numbers.....

Gotta question. What is the combustion chamber CC going to start out at on these?

I look at it like this. Find out the final cost on any decent 'Stage 2' ported LS6 head. I'm talking a TRUE LS6 head, not an LS6 STYLE head. You're going to end up paying 3,000 for any good set of cylinder heads.

Who is going the fastest? The person that spent the most money in the right places.

The power for any motor is in the cylinder head/camshaft selection/intake.

As Brian stated, there's more to this than the flow numbers. The AFR head is a better casting than a factory piece...i.e. thicker deck, smaller water jacket allowing more "meat" around the ports, already comes with bronze guides and large seats installed, intake ports start life at around 170cc's (as cast prior to anyones portwork) so the cnc work cleans up nicely, chambers also start very small so many chamber shapes/sizes are available w/out the need for welding

....the list goes on. Certainly, the benefits would be more advantageous on a high HP build up where the integrity of the head comes into play.

Hey Brian,

If this is a Stage III, will TEA offer their own stage II port of the bare castings for stock cube engines? If so, what will be the price?

These heads are clearly not targeted at someone who has a $3000 shortblock, more like someone that is trying to make 800+ RWHP and keep the gaskets on the engine. With the bare castings in the $1400 range, we are only charging around $1600 for all the labor and parts, not too bad a deal for a head that can make 1560 HP and hold the gaskets!!

They will start at 67cc, we have a 3.900", 4.000" and 4.125" bore chambers

That would be correct, we also have a 228cc program that flows 320 @ .600" on a 3.900" bore and would be awesome on a stock shortblock, unfortunately it is still the same basic price.

The exhaust flows in the 270-280 cfm range with a pipe, the small program (228cc) will accept a 2.05/1.57-1.60 valve, the larger port (238cc) will accept a 2.08-2.10/1.60 valve. The ports are extremely high velocity, I would say the highest in the industry.

We will most likely offer a Stage 2.5 head as well. Pricing will be discussed in the next few days. I will be in and out this week, getting ready for my classes to start and getting things ready for school to begin. Give Brian Tooley or myself a call at the shop for any questions you have.

They are actually very close in flow, the biggest advantage of this new head is the head gasket retention. We feel that the average street engine on pump gas will make about 1.5 HP/CU. IN. at the crank, which is around 519 on a stock block, or over 600 with a 408. Our 5.3 Stg 1.5 head has already made 540 HP on a stock shortblock and our LS6 Stg 2.5 head is better then that, so the bar is not going to be raised much higher for REAL RWHP. However, all of these guys that have been trying to make BIG power (800+ RWHP) are going to love these things, not only for the fact that they will make sooo much power, but also because they will hold the gaskets much better!!

cool... So in some words, your saying they really aren't much better, for N/A power or less than say 550rwhp.. ?? but once a BIG power adder, or you DO have gasket probs.. then consider these, a must !!

i was curious how they hold the gasket better? isnt wether a head lifts off the block based more on the hardware used to hold them down? I know they have a thicker deck. Are you saying that stock casting heads are bowing instead of stretching the head bolts/studs and that these thicker decks will prevent that?

Thanks....

So what is that exact exhaust flow numbers on these heads?

It looks like AFR really did their homework with these heads. Seems the thicker deck height on the AFR's will help with keeping the heads down in big power applications

Are these numbers with the same Ti intake valve as with your big-dog 6.0's you posted a while back?
