If ya got a "lil porting" go with some big porting. A bigger carb would prolly give ya some more top end too (38tmx or 38A/S). Bump the compression up if you haven't already done so.

I'd say the same thing too.

port it more and put a big bore cool head on with small domes like 19cc or even smaller to raise compression
