sbc alum heads
I had a set of both Pro Com alum heads and still have a set of 180/68cc AFR street heads. There is no comparison in the quality, but AFR's are going for almost 1500 new. The people who bought the Pro Comp heads (still on engine) are happy with them but they are not die hard top level racers. On a street motor the Pro Comps should work ok but will not flow even close the name brand heads out of the box. JMO Zip and Hink, what do you think? Mep
