Where your willing change stall, carb etc .. Got decent gears it's kind of up to you how wild to go, ir3333 tends to be very conservative with his recommendation others are all out, and most are in the middle somewhere I'd say intake in the 225-235 degree, 108-110, .500 ish lift range. But it's really up to you where the best compromise is.
Unless the cam you got now is killing lots of low end probably ain't gonna change much there. Stall probably give your best gains if looking for more out of the hole power.
