Planing Cylinder sealing surface of the heads

It is a common problem that the surface is not straight as the heads are bent after a long period of use. TwinSpark is able to peel off the surface until it is completely straight. The difficulty of this job is that the heads must be clamped for 100% flat therefor the modification is only possible during the complete revisions as we have to remove the valve guides.

Price is for a set of 6 heads
