You should measure the deck height of the new set up.
Put the new pistons and cylinders on with the old base o-rings.
Bring the piston to top dead center.
Put a straight edge over the cylinder directly over the wrist pin.
Then measure the gap with a feeler gauge.
Ideally the gap measured here plus the thickness of the head gasket should equal between .030 and .035.
Try this when doing a top end fit for head gaskets, you may also want to clay the heads to be sure of valve clearances
