The Process of Cylinder Head Remanufacturing

Inspect cylinder head before teardown.

Disassemble cylinder head – remove valves, springs, cam (OHC), etc.

Check for warpage – check surface of cylinder head and line bore on OHC to ensure camshaft alignment.

Thermal clean – bare cylinder heads are placed in an oven for several hours. Baked grease is then removed using shot blast for cast iron cylinder heads or glass bead for aluminum cylinder heads.

Check for cracks – maxnaflux cast iron cylinder heads; pressure test aluminum cylinder heads. Check and repair all damaged threads.

Repair cracks – weld cracks in aluminum cylinder heads or stitch cracks in cast iron cylinder heads & install new valve seats when necessary.

Straighten cylinder head when extremely warped: this process involves mounting the cylinder head to a metal straightening plate, shimmed and torqued, then placed in a 500 degree oven for four hours.

Machine valves to factory specifications.

Machine valve seats – repair or replace valve guides – valve guides must be within factory specifications.

Resurface Cylinder Head.

Check valve springs to ensure proper tension and height.

Install new valve seals.

Reassemble cylinder head – all moving parts are pre-lubed to protect from dry start; a heat tab is attached to the cylinder head; the cylinder head is then reassembled and bagged to protect it from contamination.
