Cheap Magnum Heads and some porting

If the exh seats are pitted they will need attention ie valve job. Have the valves faced, and back cut the intake valves. Don't be surprised if the exh valves wont clean all the way up on the face. I'm doing the same thing with a set of Magnum heads. Just some mild port work and a good valve job. Gonna use some Chevy LS retainers and Beehive springs.
