An aggressive trail port would be your best bet. A "dune" port job is much more suitable for 3/4 to WOT running, while a "drag" port job is for, well, you know....maximim power at maximum throttle. An aggressive trail port, however, will work to improve power in the midrange and may boost bottom end a bit, too. This is the most usable port job for average and frisky riding in most conditions.
I have an aggressive trail port and some head work done to my engine by KOR, and I am happy with the results. Big improvement over stock. A 4mm stroker crank is next on my list to further improve performance. Time and $$ will tell how that works out.

so with an aggressive trail port will i lose power in the top end? also whats a shaved head? ive asked before and ive heard many different answers.
you should gain some more top end with the aggressive trail port, shaved head would be taking a bit of material off the mating surface to lower the overall volume of the chamber, which would increase compression and would help a little in the mid range, getting the head reshaped would yield much better results than just shaving the head.
i think that will be on the to-do list when i get some money for the blaster...BTW do you need to run a higher octane fuel when you get higher compression?
Too true, ya better listen to this Blackwoods Ghetto bumpkin, ya hear.
Depending on how much compression increase, you may have to up the octane level.
Depending on who you have the headwork done by they can tune it to the fuel you want to use. I can get race gas from the pump so 100+ octane to me isnt out of the question.
What do you mean you can get race gas from the pump? are you saying you can buy race gas from a normal gas station in your area, or that you can raise the octane level in regular pump gas somehow to turn it into racing fuel? Im just confused about what you mean, im not saying i dont believe you.
