Mcx 270 kits run a .090" head shim. They run around 16lbs at elevation on pump fuel. The older alpine kits ran a 0.060" shim for a little better throttle response. But had to run a 50/50 race fuel mix. These are kits are on the nytro motor.

Or buy EVO big chute turbo, switch on the dash to run 210hp on pump gas or flip switch with 100ll to 275hp and NO head shim on either. Buy the flash and make it a 220-285hp kit...again..no head shim.
