We undertake in skimming both aluminium and cast cylinder heads to a high standard. It is advisable to have your head skimmed after head gasket failure or if it has been removed to repair cam belt failure.
Valve Seat Cutting
We cut valve seats as sometimes they can distort due to an overheating engine. A high milage engine has valve seat wear, re-cutting the valve seats ensures an excellent seal between the valve and seat.
Cylinder Block Boring
It is necessary to rebore the cylinder block when the cylinders have either, become damaged or excessively worn. In the case of a competition engine we rebore to increase capacity.
Flywheel Lightening & Balancing
Competition use: removing weight from the flywheel to make an engine rev easier.
Competition use: crankshafts are balanced for a cleaner, smoother rev range.
