The engine I plan to initially use is a 1971 360 bored +30 with new hypereutec pistons, a Mopar Performance 484 lift cam, ported J heads with 2.02 intake and hardened seats, and generic under the steering headers of unknown origin ceracoated after blasting. I built this engine 30 years ago and want to see how it runs. With the gas available then I shaved the heads to add compression back lost to flat top pistons. The engine is disassembled for cleaning and I want to do something about the surface rust in the heads. I may pull the valves and go over them with some sanding rolls.
