heads question plz help
a set of LS6 heads ported should be pretty comparable to an aftermarket set of heads, the best idea is probably to go with which ever is more cost effective.
also i've heard from a head porter that the difference between a stage 2 and stage 3 port job is only about 8 hp and about $200... to me that is probably not worth it, stage 2 should be fine.
btw: don't forget to take advantage of the search function of this website
