I have a set of ported and polished 7.3 power stoke heads with the hyper max rev kit ,stainless intake valves,inconel exhuast valves.These are also grooved for o-rings and I have brand new (still in box) gaskets and o-rings from hypermax.I took these heads off when I sold my 2000 powerstroke and had a machine shop check them out and clean up.they are sealed in plastic bags and on my shelf.1200.00 plus shipping will get them!!!
