You better get the clay out and double check your clearences .I don't think it will work but if you need one I have a brand new 52 mm superhead piston and rings for the old style $85.00 shipped.The superhead has a different dome than all the other heads and makes it hard to get other brands or models to fit.

I have both pistons here the r stage and the superhead and it's not even close.The old 70 chamber is way deeper than the superhead.I already tried this in the spring with an old style 70 head high comp. piston and spent hours grinding and claying and it doesn't work.
