cam question

i run ported and matched 302s with 1.60 exhaust valves on my 360, it keeps pulling til i back off at 6000, with the 284/484 in a 318 with these heads it would wind up to 7000 no problem. with present cam ,489 lift from bullet racing and previous MP cam i ran comp 901s as per engine shop recommendation.these heads will flow with good velocity, never mind the number crunchers, try things out for yourself and see what happens
