hardened valve seats L78

[JBB]

Hello. Since the original L-78 was blown in our 69 SS Camaro
in 1984 doing a 12.49 Quarter mile, I am in the same position. After asking numerous shops about the valve dilemma, most engine builders want to have stainless valves and seats installed, especially if you have the 11. to 1 compression pistons that were stock in the L-78. I will have this done, as well as using the lead additive that is advertised by Jack Podell in Indiana. Unless you own a gas station that sells 114 octane leaded fuel, I think it is wise to have the heads done.........
