All said, I ran your performance #'s and considering such a small cam and assuming you don't have trick ring packs and vacuum pumps and great valve jobs...YOUR MOTOR IS MAKING DECENT POWER now for the compromises. I'd guess you'll need about 50hp? or so for your stated goal? ...I don't see just a rocker change giving you that much but if you did both (well 3) things I suggested it should get you there assuming you don't have a plenum spacer and shear plates. Also as stated your maintenance interval will go up...lifter rebuilds? spring change intervals? with cam intensity. Maybe look at a PAC 1225 spring on the intakes.
