Magnum heads and cam selection??

Well as far as cam selection for a mag,dont get a dual pattern cam. They dont need the extra help on the ex side. The port there is very good. Get a single pattern cam for a mag. I think this is a fairly unknown thing as far as mags go. In fact I sometimes see 1.5 ratio rockers on the exh of a mag in an attempt to restore flow balance. It's part of the secret in how to get a mag to perform.
