Street HEMI CNC Head Porting Monthly Special

HEMI Machining

FHO heads are machined on our RMC V-50HP 5 axis head porting system. We have digitized our best flowing ports, and offer heads with consistency not possible with hand porting. Our heads feature fully machined combustion chambers and ports, and are offered in multiple head designs.

These max port designs come with enlarged pushrod sleeves installed for added clearance. Optional intake flange machining for Viton O-rings, deleting the troublesome intake gaskets. Includes full radius valve job and assembly to specs.
