Where to buy a Multi layer steel headgasket for my 71 CB750?

Cycle x and dynoman have them. But you do know you are supposed to have the correct surface finish and the surfaces have to be absolutely flat to use MLS.

Machine shop is taken a few thou off to make sure the head is true.
should that be enough?
 
Head and top of cylinder both need to be flat and have the correct finish...not just a normal surface finish, make sure you specify for mls but .doing only the head is putting a bandaid on half of a cut. MLS gaskets do not compress and dont conform to imperfections which is the reason they have to be flat and have a fine surface finish
 
If you dont have flat and fine finish it is easy to have oil leaks with the MLS
