318A Camshaft

I'm looking at rebuilding the heads in my poly motor and I want to get a bit more performance out of it while I do. I'm going to get some work down on the heads to open them up and I want to upgrade the camshaft at the same time. Any suggestions where to look? I tried searching the yahoo poly group and the 1962to1965 site but had a hard time navigating them. Thanks for the help,

David
