"Did you guys change to .030 head gaskets or just bolt in the CR 575 cams? "
Did not break the head at all. Stock gasket, just used full complement needles on the cams, put in the CR575, Hi FLo K&N and DnD FatCats. Torque peaks around 35-3600, and power around 5100. No additional valve train noise that I notice, although the Fat Cats are considerably more beefy sounding than stock! Like a NEW BIKE! OH< BTW, no longer cooking my right leg either!
