My son is selling a Pair of 340 x heads he was saving for a project but sold it. They have the 2.02 valves and no port work but we’re on a friends running 340 for about 500 miles. They had new guides, valve job and valve springs for a hydraulic cam up to .550 lift. They are dated 1967 I guess for 1968 cars. He is Asking 1200 obo for the pair. Prefer someone pick up in person in Leitchfield Ky but I can ship if needed.
