When I did my heads/cam swap I bought Felpro gaskets, since they were available from the auto parts store. After installing them, there was an immediate leak. I had a few others left over, so I tried them too. In total, 3 sets of Felpros all leaked.

As you can see the problem lies in the fact that the primaries are circular, while the ports on the gasket are not. The holes on the gasket are too wide, which keeps it from sealing around the edges. The gaskets from Pacesetter have circular ports which mate up much better with the headers.
I believe anyone who had success with Felpros just got lucky.
