can i use the stock head on the 80 polini? havnt been able to find anything... and how big/much should the case matching be? i know to do it to the size of the gasket, but how deep?and while looking through other threads the 2 transfers on the top and bottom of the case were taken out... this is the pic i am refering to.
but he says it was for an 86cc kit and the piston skirt would hit the case, so is that why he got rid of the 2 top and bottom transfers??? dose the polini need them ?
