    GPR 1300 head gasket

    I read somewhere on GH that the '05-07 1300 headgasket has better coolant flow than the previous years; would this be a good "upgrade"? I'm adding a higher comp head and replacing the gasket on my '03. If the later models flow better, I'd rather use those.
    Anybody done this before??
    Thanks,
    j.p.

    Yup, run it on my ported motor. Better cooling for #3.
