RI Engineering

Advanced cylinder head resurfacing at affordable prices with fast turnaround. Flatness is key to providing the optimal mating surface for both performance and reliability. Our typical flatness less than .001" over the ENTIRE surface of the cylinder head, end to end. This far exceeded OEM specs and traditional engine machine shops can't touch our tolerances. You want your cylinder head back in days, not weeks. With lapping, you never need to disassemble your head. Leave the valves, springs, plugs, cams & gears in place. Pull the head and bring it in. Trust the experts.
