I have a set of Trick Flow 175 heads with the 1.460 double springs (rated for .600 lift) with 700 miles on them. They are centerbolt heads with the standard intake bolt pattern (not the '87 and up iron head pattern where the center bolt hole angles were changed). The info is on the trick flow site, but they flow about 242 CFM max and have 56cc chambers. They also have ARP 7/16 studs and ARP head bolts included.

Local pick up only in Columbus, Ohio.

$845/pr
