    05 RXP head work

    I am going to upgrade my exhaust valves, While I have the head off I was wondering if I should buy the 08 rocker arm shaft and rwemove the oil pressure jet in the block, or to go with the new oil pressure jet for the 04 / 05 engines?

    I think I am going with the 08 rocker shaft and removing the oil pressure jet. That way when I spin more RPM I can drill out the 2mm hole to 3mm to increase oil flow to the head

    Its a lot cheaper and easier just to install the pressure jet, i dont think the rocker shaft setup is any "better" on the newer models, its just a diff oiling system (i think)
