Ok, to find out what heads you're running you'll have to get a casting number. I dont know where exactly on the head it is, can anyone help on that. As far as I have read those conversion kits, turn your old stamped fulcrum bearing rockers into roller bearing rockers. They do not let you run the aluminum adjustable ones. You would have to have the heads machined for screw in studs. that is not that big a deal, other than the fact you have to remove them. while they're off you could also have them milled to raise the compression. If you do, mill them , and go with a 1.7 ratio rocker, and a bigger cam make sure to check the valve clearences so all that work does not go to waste. Hmmmmmmm as long as the heads are out you can always go for the 3 angle valve job too. Oh and if they are old make sure you have hardened exhaust seats installed.
