We manufacture watercooled Billet cylinder heads out of specially heat-treated aluminium, that has a significantly better heat transfer capabilitiy and is more durable compared to cast-aluminium.

Our cylinder heads are available "ready-to-install" for all engines that have a capability to get custom size ports and combustion chambers.

Heads are available fully "ready-to-install" into engines that have the possibility to be fitted with custom sized combustion chambers and ports. Heads are designed with the latest 3D-software so that for example the ports are manufactured directly 5-axiallity with the Mastercam Port Expert -software.

Material for valve guides etc. can be customized to meet the customers' demands.
