vforce reeds and bump up the timing, maybe get tors eliminated to save the hassle when your jetting. i also like the lightned flywheel and some good tires. cant do much without traction..
i like the noss head and do yourself a favor and have your crank trued and welded if you plan on bumping the compression up. i would go with 19cc domes with the race gas but that depends on dome design, porting, and timming. you might want to talk to whoever is porting the cylinders to see what they recomend.
