you wont have to run race gas if you just polish the flow channels... if you cut the head, or cut the ports then 95% of the time you usually have to run some type of race gas.... You want alot of bang for your money?? Match the cases and polish the flow

so match up the transfer ports? i don't really want to remove alot of material and especially not on the cases since i just put that brand new crank in

No race gas needed..... In my honest opinion though gas is not what it was 5 years ago and it was so-so then. I tried to modify pump with some success and ran that for a while but the stuff I used to modify the pump gas is no longer available so now I run C12 or some other form of race gas.
