Racing Head for GX240 & GX270 with Genuine Honda Core

All heads use Genuine Honda cores. (These flow better, are less porous, and stronger than aftermarket heads.) Heads are ported, bead blasted, flowed, and milled. Heads can be fitted with either single or dual springs. Single springs are recommended for 306 and smaller cams. Dual springs are recommended for 307 and larger cams.

High-torque heads use small port castings to increase velocity and maximize low-end power at loss of high-end RPM. Best for most applications

Maximum HP heads use large port castings to increase high RPM power at some loss of low-end torque
