Hey bud, I was looking at those heads on Texas speed website, but they don't specify what kind of flow plate it used to get those numbers. I'm stuck between those and the PRC 237. Do u know what flow plate they might had used?

Im gonna build a 408 as well. what weisco pistons are those? Looking for close to 500whp. Think that is possible with EPS custom grind cam (like 236/248) TFS 225cc heads with a 92mm intake and TB?

these are the reverse dome pistons, but they are for nitrous so..id say a custom cam in the mid 240s 250 would get 500whp!!
