Tri-Z head

[bluevetteguy]

I was repairing a busted radiator hose yesterday and noticed something on top of the head. Its got the yamaha tunefork emblem on it. They didn't start using that until the mid 90's did they? I don't really know a lot about yahamas. The emblem is on the right side and is about 3/8 of an inch (don't know if they put it in the same place every year for ID purposes)
