The Parts Unlimited pistons are probably cast pistons instead of forged like Wisecos. For normal use, they should do fine. In most engines, cast pistons work with less problems than forged, as the pistons heat and expand at the same rate as the cast cylinders.

Thanks! i just wanted to make shure they don't wear out fast or have skirt cracking problems. Now ill do new pistons in all three cylinders for shure instead of rings in two and piston in one.
