Cylinder Head Machining

Especially in high-performance situations, cylinder heads can become damaged through a variety of problems ranging from head gasket failure to cambelt failure. Returning the head to optimum performance involved a range of skills in head reconditioning all of which are available at Fiennes Performance. Our specialist cylinder head services include valve seat cutting, valve seat removal, valve guide removal and refit, valve grinding, head reface and essential hot pressure testing to check for minute pinholes or cracks that may cause future failures or loss of performance.
