p73 pistons won't yield much compression in a b18c1 block and head, it should put you at about 10.5:1 or so. PR3 or p30 would yield higher which is suitable for pro2's. Also, milling the head and a 2 layer headgasket would bump you up as well. You can use an OEM headgasket and just take off the top layer which is the same thing as the mugen 2 layer.
