CONCORD, N.C. – WKA has made an adjustment to the head gasket rules for Clone engines, effective immediately.
The WKA Board of Trustees voted last night, November 20, to change the Clone head gasket rules. Minimum head gasket thickness is still 0.008”; however, there is now NO maximum thickness on head gasket.
The 26.5cc minimum volume in the combustion chamber rule will remain intact.
The use of sealants on head gaskets on Clone engines is now LEGAL.
This change is to make the head gasket rule more in line with the current head gaskets being used as well as being user-friendlier.
