    correct me if i am wrong, but i believe that the 67x is a "Riva Thing" because they have 800 and 1200 heads that begin with 67x and also you will see 67x on xlt1200 motor mounts from Riva, as well as some of the gas valves that they sell.

    If you have an 800 or 1200 cc boat, then be sure its for an 80mm piston and if you have a 1300- be sure it's for the 84mm pistons. You will know quick if its the wrong one.

    It's not originally a Riva thing. I'm sure they use it, just like a bunch of resellers and marketers do.

    The 67x I dont think is specific to a model, but to some parts. I see it on the coupler for the 2002 and up gpr, etc... lots of parts.

    66V is the designation for most 1200PV engines.
    66E was for the 800Pv
    60T was the 1300Pv
    I forget what the 1100 and 1200NPV engine was.

    The 1200NPV is 65U, not sure about the 1100 either.

    that head is off a 2000 gp1200r with power valves. The only reason I know is because a friend just remove that numbered head from his ski.
