    Pistons Valve relief...

    Just bought some pistons for my build i went for 83mm stroker pistons
    9,5,1 compression for my k04 hybrid stroker build check these out

    these are CP Made by carrillo some mighty valve reliefs on them !
    i wont be using high lift cams though maybe in the future

    come with some nice features i like the idea of the double pin oilers

    yeah your right don't quote me on this but i "think" the guy from pagparts had some influence on the design
    of these just what i caught from the U.S sites but maybe wrong ...

    Right here is some more pics ....

    I was going for some Mahle Powerpak pistons but i haggled a good price for these
    and there seem to be highly rated by some people for my use the valve relief
    is pretty excessive but for any future projects maybe of of some use to
    accommodate oversize valves with high lift cams inlet side....

    As you can see there doesn't seem to be allot of meat between the valve
    relief and the top ring groove
