Hello all--I am restoring a 1971 Honda CB 750 K1 motorcycle. We are about to reassemble the motor, and one source recommended that we use a multi-level steel (“MLS”) head gasket, after the cylinder and head are decked and re-planed. Apparently, MLS gaskets were not used on this model originally. Do those in the know recommend this approach and if so, can anyone refer me to a source for the MLS gasket to fit this motorcycle? Any other comments or suggestions would be appreciated. Thanks, Rob Gibbs.
