Tips on powering-up a 650L?

Does anyone have any tips on boosting the power on a '94 650L? I am currently rebuilding it because of a "stripped" second gear in the transmission and figured I might as well put it back together right. It is a CA model with the smog block-off kit installed, and has had the Baja Designs carb-kit installed, too. Supertrapp muffler with stock headers. Any thing I can do to the engine or heads to improve the power? Porting, cutting valve seats, different piston, etc.?

Thanks for any input.

Thanks for the link-- some good ideas there. I've already done some of them, but will try a few more, too!
