60cc CNC-profiled combustion chambers combined with a state of the art valve job and CNC blended bowl work under the valves and small cross-section intake runners promote low-RPM torque increases and boost high-RPM horsepower. The runners are finished with Trick Flow's superior Fast As Cast process that precisely duplicates the runner profile and performance levels of fully CNC-ported heads without the added machining cost. Ductile iron valve seats for use with unleaded fuel, stainless steel valves, bronze alloy valve guides, multi-angle valve seat machining, and decks and walls cast extra thick for increased casting strength and to provide extra room for porting round out the features.
