HEMI Head Machining

At FHO, we built our reputation on machining hemi heads to the highest standards. Whether your heads are used, or new castings being prepped for competition, machining and tolerances are maintained at the highest level. Many head machining operations are performed in our 5 axis CNC for unmatched accuracy and repeat-ability.

Our final seat cutting/valve jobs are performed in our Rottler head system utilizing custom FHO full radius seat cutters. Durability and improved performance are assured at FHO.
