Upgraded ZZ4 cylinder heads SOLD - F-Body Road Racing and Autocross Forums

I plan to swap heads on the Camaro engine before it goes into the Corvette. So, I have a set of Corvette/ZZ3/ZZ4 cylinder heads for sale. They were redone with Manley "Race-flo" under cut valves (1.94/1.50), K Motion K-750 springs (130 lbs on seat/380 lbs open), Comp locks and retainers (or Crane, I forget which, but good quality 7 degree stuff). They have 7/16" ARP studs and guide plates (Comp, crane, etc, but good quality guide plates). 1,200 miles on them total. They were lightly skim cut to make sure they were flat. The intake ports were radiused to fit a 1205 intake gasket. Multi angle valve job was done when the heads were setup by my machine shop.

$695/pr OBO (just the valves were $300+).
