Good job on getting those numbers.....![Happy](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_stretch.gif)

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

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?

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.

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!!
Awesome news! I may have to look into a set

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....
Thanks....

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