The LSA heads are a better casting just like the LS9 heads. Definitely good for boost. They do have a cast in (wing) inside the intake port that you should knock down with a grinder to improve flow. LS3 intake bolts right up and can make great power even in stock form (I have gone 163mph on one and lots left in it).
