Best heads are propably some of the new aluminum heads. If you are looking for production heads, any open chamber head is good, and the '915' closed chambers with 2.08/1.74 valves. One important thing with the heads; combustion chamber size. Aim at about 9.5:1 compression ratio if you are going to use pump gas. If you are going to port them, have bigger valves installed and port the bowls. I don't know much about the camshaft in this case, but think that a cam with about 2-5000 pulling range would be good, ie. not too big.
