Noticeable increased performance through optimisation of the existing material
The intake and exhaust ports are reworked to increase performance, so that the mixture is better swirled and can enter the combustion chamber with less flow resistance - this measure is far superior to simply polishing the ports, and the execution of the work requires a great deal of know-how
Scope of work: Reworking of the intake and exhaust ducts, correction milling of the valve seats, flow-optimised adaptation of the valve guides and the intake manifold, planing of the cylinder head sealing surface
