AI 226cc 243/799 heads for a NA 383?
Going with a 383 ls1 for my TA and don't have the coin for AFR or trick flows. Would these heads along with a Fast or Bbk intake and custom cam be a good combo?
Would like upper 400hp range with a good healthy tq curve. Compression will be around 11:1 and be a mostly street driven car.
Or would the AI 232cc heads be better or am I way off track? I tried searching,but everyone is iron block 4" bore crazy, so not a lot of info anymore on the little aluminum 383.lol

I think if you are on a budget, Texas Speed PRC LS6 heads will be the best bang for the buck and over all less money than AI.
You will be comfortably over 400 hp with a mild cam.

Ehhh....I think 500 ponies to the ground is pushing it for a 383. I think you would be close at upper 400s.

This is a slightly larger version of our 226cc CNC work that has consistently outperformed other CNC'd GM castings on the market, as well as most aftermarket casting based heads. The 226cc work being only slightly larger than the as cast port, would often leave some areas in the intake port untouched by the CNC cutting tool. While this is aesthetic and does not negatively affect performance, this slightly larger version will minimize or eliminate these areas of "non-cleanup." Most applications will not be negatively affected by the slightly larger intake port, and LS2's & strokers will pick up another few HP over the standard 226cc CNC work.

It won't hurt anything, that's for sure. But the point I was making is that with a smaller engine (albeit with a slightly larger bore) and a pretty mild cam (232/236) you can do 500+ with the 226s. You just have to make sure the rest of the setup is good.
