Incorrect. The LS3 heads are great heads and are not really worth touching unless your over 500whp. Here are some dyno's on STREETABLE cams, not giant surging beasts, on untouched LS3 heads. First link is 2 separate cars with different versions of LG's G6X-3 cam. Second link is Carteks contribution. I promise I know what I am talking about, at least with regards to LS3's
