Process & Warranty
Cylinder Head Rebuilding Process
1. Initial Inspection: As a unit comes to our shop, we give it an initial inspection to determine whether there is any reason the head should not proceed to rebuilding. This quickly catches problems such as cracks, casting damage and other conditions that would halt the process for that casting.
2. Teardown: The cylinder head is fully disassembled, which reveals other areas of potential damage to the casting. The parts and the head are separated and go through different cleaning processes.
3. Cleaning: Cast iron heads are cleaned in a thermal cleaning system — baked at 600° to reduce grease and oil to ash, then put through a steel-shot machine for a brilliant finish. Aluminum heads are baked at a lower temperature or put through a high-pressure wash, then glass-beaded.
4. Head Inspection: After cleaning, heads are pressure tested or Magnafluxed to find any cracks. All bolt holes, valve guides, valve seats and other areas are inspected for broken bolts, broken taps, cracked guides and other impairments. Straightness and cam bore wear are also checked.
5. Machining: All heads have guides installed to meet OE conditions and are resurfaced to far exceed factory specifications for surface finish. A three-angle valve job achieves valve seat runout under .001". Valves are ground for a perfect seal between valve and seat.
6. Assembly: New OE-style valve guide seals are installed. Springs are tested for proper seat pressure. Valve seat sealing is vacuum-checked for an airtight fit. Lifters are bled and rebuilt for zero lash after startup. Cams are polished and clearances are checked twice to meet OE oil clearances.
7. Final Inspection: Every head is visually inspected — surface finish, lash, bolt holes and all other areas — to ensure a quality cylinder head.
