Having inspected all of the new cylinder head castings available on the market, we have found most to be of inferior quality (poor castings, porous material, improperly machined cam journals etc.). We have chosen a manufacturer that uses a different material that is less prone to cracking and electrolysis (corrosion of the cooling system passages).
 
Even though we start with a NEW casting, it’s still not good enough, we improve it even further. First, we resurface the new head for a better gasket sealing surface. The exhaust seats are removed and upgraded to a harder powdered metal material. A three angle grind is performed to match the new intake and exhaust valves we install. The valve springs are individually tested, new valve stem seals are installed and valve stem height is checked.
 
CAMSHAFT: We regrind factory camshafts ONLY since they are made of superior material. We will NEVER USE THE NEW CHINESE import camshafts. We have had them inspected and have found the material used in the new cams from China are made of a material that is WAY TOO SOFT and will wear out extremely quick. We will not cut corners for price.
 
ROCKER ARMS: We have the factory rocker arms remanufactured ONLY. We have found the geometry and material of the Chinese import ‘new’ rockers to be VERY inferior. We also install NEW valve adjusting screws for the best reliability.
 
ROCKER SHAFTS: We use only NEW hardened and chromed rocker shafts that have a higher oiling capacity for better reliability and performance.
 
The 22R / 22RE is an extremely reliable engine, we build only quality cylinder heads and will NEVER cut corners just for price!
