Is 4.125 the part # size or the skirt dimension where the manufacture requires you to measure?

check with the piston manufacture for bore to piston clearance. they range from .004 to .007 for forged. i'd say you'll probably be ok with the .005 you have now.

will be fine,just make sure the bore is true all the way through.use a dial bore gauge to check it..big bore and short stroke is the way to go.
