    2004 on 2008 block

    Greetings,

    Has anyone ever done this? I am looking to put a 2004 head on a 2008 block to build a spare race engine. I see the 2004 has the restrictor in the block, and the 2008 does not.

    Should I put the restrictor in the 08 block, or is there something I remember reading about the rocker shafts?

    Any help would be great..

    Thanks

    The restrictor is in the 08 rocker shaft.You don't need the one on the block 04 with the 08 rocker shaft.

    if I have the 04 rocker shaft can I just put the 04 restrictor in the block and be done with it, or is it better to take the restrictor out of the block, and put the 08 shaft in?

    Thanks

    The 06+ rocker shaft restrictor needs to be drilled to (3-3.5mm)for high rpm motors, if you decide to go with the block restrictor go with the Rotax Racing one. I would go with the 06+ rocker shaft.

    dont drill anything in the rockerarm shaft , that was just a forum hype !

    just make sure you use a 2006-2010 rockerarmshaft

    for your turbo setup you absolute dont want to loose oil pressure , so dont drill anything bigger !
