i read the entire imno post abotu how me milled the pistons completely flat and milled the head .0060

what if you dont mill the pistons, how far can you go with a pr3 head until you have contact with the b20b piston? and at that point what will your CR be?

 

What ever you do to raise the compression, you need to mill the valve pockets on those pistons. You best bet, get new pistons and rods or just leave it alone.
