393 HP is the steel head the 422 HP is the bogus approved aluminum head that won't pass tech without changing valves, seats, guides,oh yea the CC's are way off exhaust & intake so milling int. side makes it fitting the intake a little tricky, exh. side careful not to mill into valve cover holes/bolts, just kidding, but no epoxy, just shoe boxes of money, Can be done but advantages/gains AAH!!!
