Just wondering what a nice set of well ported 587 heads are worth ?
MP 2.02/1.60 valves
Flow 260/173 at .600 lift
bronze guides and hardened exhaust seats
Crower dual springs
Comp 10deg retainers and machined locks
60cc chambers
Built by Dwayne Porter of Porter Racing Heads (Fast68Plymouth on Moparts)
My motor made 480hp with them and went 11.60 @117mph in a 3600lb car.
