Hi there I ran into a problem. I need only a head gasket for my 1980 honda cb750F. but everybody wants to send me an entire gasket set, which I don’t need, I only need a head gasket. I ordered a one for a SOHC, bu that doesn’t exactly fit the DOHC. I did find one but it was like 89 bucks for just the gasket, can anybody help me out?
