I just lapped all the valves and replaced the valve seals on my 72 cb350f I have a couple of heads laying around and noticed the valves in the head I'm working on have a logo on the bottom of them that almost looks like a Mitsubishi three diamond logo. Are these stock? Not that it matters much but I'm curious and didn't recognize the logo. I'll post pics later
