We offer a complete cylinder head reconditioning service. We can re-machine the gasket faces, replace valve guides, valve seats and valves. On older heads we can convert them for unleaded fuel.
Cylinder heads can be pressure tested on our ‘Delta Custom’ pressure testing machine to find any cracks or leaks. This test is highly recommended before any further work is carried out.
Valves and valve seat angles can be cut on our VV80 valve seat cutter.
Cylinder heads can be skimmed or refaced. For aluminum heads we use a polycrystalline diamond tool bit, and for cast iron a cubit boron nitrite bit is used to ensure the correct surface finish
