Shaved Heads

possbility of 70cc stock heads is pretty slim, with mopar you never know though. you should have milled the intake face of the heads rather than the intake, just for interchangeability somewhere down the line if you wanted too. I would try and bandaid the situation with some thick head gaskets and see where that got you. i have 56cc j-heads and rocker shims to keep my setup working. stock 318 pistons/rods/deck height
