I have a 2000 Banshee with Toomey T-6 pipes, K&N dual filters, and Toomey jet kit. Looking to shave the head .30 but not sure if that is the best head mod. Any recommendations? Looking to get a little more compression and possibly run VP 4.2 race fuel if necessary due to increased compression. Thanks...

Cool Heads. You can change the compression to what ever you want. Elevation plays a big part in comp.
