Mid 12's, buy a set of reconditioned Indy heads for $500. They come with new Stainless 2.02 / 1.60 valves, bronze guides, springs, seals, locks, retainers. Take them apart, pocket port and gasket match them, and that should put you in the mid 12 range on the cheap.
On these... where do you buy reconditioned Indy heads.. I wouldnt mind finding a set of 360-1s at a reasonable price
