BUGPACK SE COMP Heads
S/E™ Comp Heads are the result of Bugpacks extensive head development program.
As with the S/F™ Heads, these brand new heads are built from the ground up — not redone!
The main objective was to bridge the “gap” between all out race heads and reworked stock
heads and that mission was more than accomplished. It will be necessary to modify your stock dual port end
pieces to match the intake ports on the heads to run a single carb. Just check out these
