the AI CNC TFS 208cc LS1 heads are designed for a 4.00" bore LS1 and they AI told me that they will work well on my 3.91" bore LS1. i just wanted to see dyno and track numbers numbers for these heads before i decide to buy them.
btw, i have touched up (lighlty ported to 218cc) CNC TFS 215cc LS1 heads ported by Chris Frank@raymac racing engines in my house but i want to see if the AI 208cc TFS LS1 heads are better then i will go with AI.
let me know what do you think and if any one has a first hand experience.

so if you were at sea level you could be deeper into the 11's at around 125 mph. so that tells me your AI heads are very good. i think i will try the AI CNC TFS 208cc LS1 heads. i will let you know the results after install.

also I do not know the spec on that cam but if your running an M6 Ed's AZPS03 another custom cam made 420 rwhp on my buddies F-body with Long tubes and a tune only. FYI

I'm just saying that if someone has secret specs....All it would take is Richard at Big Johnson cams to take that cam and spend 25$ to get it doctored and bam....He would have all the exact specs.

AI puts out some good heads. but the TFS 215 is a proven cylinder head.
i wouldn't think there is much out there on the 205's with them being so new, but i have been wrong once befor.

I know you saw the numbers I put down with my 215s and since you already have a set lightly massaged I don't see the confusion or problem...throw the tried and true on...215s...

the TFS 215's i have are brand new and never been installed. they flow 314cfm before light porting, after light porting to 218cc they flowed 325cfm. i think the 215's i have will perform very well but i think the AI 208's will perform the same if not better and even with more torque due to smaller 208cc runner and better fuel economy.

thanks Chris for directing me to sell the 215's heads i have. first i will try the AI TFS 208's if i didn't like them i will go with the 215's i have. if i liked the AI TFS 208's then i will sell the TFS 215's i have.
