Cylinder Head Work

Mass Racing is one of the leading UK classic and racing engine specialists.  We have amassed decades of experience in performing cyclider head work for various makes and models of road going or racing classic & vintage cars.

Mass produced cylinder heads are usually suboptimal for racing applications due to being designed for maximum durability. Ports can be modified for maximum power, minimum fuel consumption, or a combination of the two, and the power delivery characteristics can be changed to suit a particular vintage or classic car application.

Contact Mass racing to discuss your classic car cylinder head or porting work requirements.

Engine Valve Work

Older engines frequently need their valves reconditioned. Mass Racing can undertake this specialist work for your engine, often known as “valve jobs”.

If your valves are bent or burnt, or they need re-seating or replacing, we have the experience and tools to optimise or rebuild your classic car engine exhaust or intake valves to restore optimal performance.

Valve jobs may be undertaken as part of a larger engine rebuild or cylinder head work. Speak to us today to discuss your needs.

Crankshaft, Piston & Cylinder Work

Mass Racing is one of the leading UK manufacturers of crankshafts for classic and vintage race & road cars. Crankshafts are often not a straightforward matter and require not just the correct machinery but the skills & expertise to do the job right – your engine depends on it.

Intrinsic to the operation of the crankshaft are the attached piston arms and piston heads – which in turn operate inside the cylinders bores in the block. None of these components can be left to chance and require accuracy in manufacture, tuning and installation. We can perform all necessary cylinder bore, crankshaft and piston related your engine may ever need.
