i have a set of part#574 heads that i bought back around 97-98 from mancinni and never used them,there the 340 replacement version with 2.02" intakes instead of 1.88".
Being as rocker gear has gotten $tupid high for my w2 and w5's i sold them and want to keep it simple,i'd like to hear some results from people who have used them,or know someone who does.
I know there supposed to be popular s/s racers as a replacement for the "308" head,but supposed to have more meat for porting i believe,replies anyone
