recently purchased a new fox, and its got a 351w with pro topline aluminum heads. i havent really heard a whole lot of good things about them but i was wondering what you guys have heard about them. i dont have any dyno numbers or know the specs on it quite yet (waiting for the paper work) anyway i was wondering if i could work these heads for more power or if it would be better to just sell em and get into some nice AFRs.
