Just got my heads back from Rimco and bought a new set of Mahle p/c's. Do the cylinders still need to be lapped? (IMG:style_emoticons/default/confused24.gif)

This is how I lapped mine [per a Porsche mechanic]
Apply valve grinding compound to the end of the cylinder, place it into the head and with even pressure rotate the cylinder back and forth a few times. Make sure you wash the residue of of the surfaces when done and keep each lapped cylinder in the same location on the head. DO NOT install the gaskets , they will leak. |
