All Ivor Searle cylinder heads undergo the same intensive remanufacturing programme, involving complete strip down and thorough cleaning.
- All cylinder heads are then inspected for cracks and distortion to check their suitability for remanufacture.
- All cam housings are checked and restored to specification; non-conforming parts are replaced with a new casting.
- Bolt and stud threads are cleaned and any damaged threads are replaced. Valve guides are measured for wear and re-sized or replaced as necessary.
- All heads are refaced to ensure the optimum surface finish specified by the engine or gasket manufacturer.
- Valve seats are machined to the correct seat angle, width and depth.
- Valves are measured for stem wear, head thickness, straightness, and are refaced or renewed as required.
- Valve springs are measured for free height, compressed load length, squareness and renewed as required.
- Cylinder heads are then assembled with new valve stem seals, valve seat seals are vacuum checked and the head is subjected to a final quality inspection and packing.
All new parts used in the process are sourced for their reliability and durability
