so from what i'm gathering, the l92 heads and the l76 intake only the LS2's can take it? well what if the LS1 guys bored the engine out to 4.00 inches and installed them. would that help at all? or have people already been doing that? i'm totally in the dark about this subject. and i also read that you could get close to 500 rwhp??? is this true or not?:lookinup: :cheers:
