Took the heads off - Clean up?
I agree, measure with a degree wheel and know for sure.
jinxedz, if you're trying to decide between a .020" or .010"- go with the .020" mill. Compression is your friend. It'll even idle better (smoother) if you can get the compression up some.

If I mill, will the Hardened TSP 7.4 pushrods I have be adequate, or will I have to go smaller?
