The KB-pistons should supposedly be able to create a 11:1cr, but since I've smoothed the sharp edges on the piston and the chamber along with valve unshrouding, I'm not sure it will still reach that number without a few more cuts on the heads.

I have however ordered thinner headgaskets (0.028")

to gain back some cr.

Any ideas of using 1.6 rockers with the XE256 cam?
