    milled head or Riva?

    I made the decision to modify my head on my 06 gpr. My question is whether to do a stock milled head or buy aftermarket. Is there any benefits of one vs another?

    My current mods are...
    Riva Dplate
    Riva EFI
    Jims FF plate
    Jetworks Pro
    Solas 14/20 DF
    PPK
    1200 grate
    Carbon Tech Reeds

    My rpms are a bit light for where I need to be and I am around 70gps'd in chop. I ride Jersey bays and Ocean and never see glass.

    I have tried several aftermarket heads on several platforms. For the GPR's I prefer the milled OEM head. Get it done by the right person and it will out perform the aftermarket's and not require any special hose routing gasketing etc.

    I was thinking of using Jim again, he did such a great job on my plate, and he was very helpful with questions I had. I just wanted to be sure it was an acceptable way to go.

    milled is stronger than aftermarket it...

    biggest pro i heard/see in aftermarket is looks....

    But you can just spray paint your head gold.... and it'd be just as cool

    I have a couple Jim's plates and love them. I have not had a head done by Jim. I have used Lowell and Pro-Tec I do not reccomend Pro-Tec as the guy who ran the shop is no longer there.

    Depends on which head you have there were two a 66V and a 67X the 66V did not require squish work to be done.
