The 138190023B Clone Coated Thin Metal Gasket is found on 196 clone engines. 

This gasket is the synthetic coated metal head gasket adding around .0015 total thickness. This coating provides better sealing versus non-coated versions. The thin head gaskets are used to gain compression on the standard 196cc or 68mm blocks. The head gasket fits the 68mm standard bore and bore sizes up to +.75mm over. The head gasket fits most 68mm bore blocks, including Clone 6.5hp 196, Ducar 196, Tillotson 196R/RS, Box Stock 196, and Honda GX200 Engines. This gasket does not fit 70mm 212 Engines.
