what are a good set of heads
the only heads i have really checked out so far were the 180cc heads form air flow research.
their flow numbers are 265 intake and 211 exhaust and .600 lift
a friend of mine has a 03 trans am w/ an ls6 in it and we just put stage 2 ls6 heads on it their numbers are 304 intake and 229 exaust at .600 lift.
are their heads that compare to those numbers for the lt1?
