idea?

[kubis21]

Alright guys its time for a rebuild...lookin for ideas...I already have a 4mil crank with long rod, punched .02 over, stock head shaved, stock carbs with tors removed, k&n pods, reeds and spacers, and a moto-fast 2in1 exhaust. Im thinkin to punch it another .01 or .02, have cylinders ported and cool head. Just wondering who to have port it, i was thinkin an aggresive trail port, dont know what kind of cool head or dome size is best...not sure how high of comp i can run on 100 octane av fuel. If you could give me some ideas on what u guys think i should do i do mostly tight, hilly trails and some mx looking for more bottom to mid power...thanks
