Your piston-to-head clearance of .050" will limit your fly cutting of the head to .020". That will reduce the step clearance to .030". If you do this, do not cut the cylinders even shorter. Calculate how much that will increase your CR, but my educated guess is it will only raise it 0.2 or less. More will require new pistons.
