That's a very vanilla question that is not easily answered.
Your heads may be ported, but at what lift do they flow the best? The two cams are very similar, but GENERALLY the wider separation will yield more cylinder pressure and torque. If you know what gear and mph you will be running the most, you can figure where you want your powerband to be at. I probably didn't help, but these, and more are very important factors.
