    Valve Relief Pockets

    I am rebuilding a 2.4 L for a stock 73.5 T and had to have custom pistons made. Went with an off the shelf Morittz design 85mm for my CIS. Do the exhaust reliefs look oddly off center?

    I think that is the characteristic of Moritz pistons,,,,like that is their attempt at recreating the offset dome of the original pistons. Do a search for "Moritz pistons" and I think you'll find more pictures of that style. Do a clay check trial assembly so you can see what the valve imprint is in the pockets.

    Thanks Ed! I feel better. Newbs have unlimited ways of generating paranoia. I had wondered if other engines somehow had the exhaust valve offset to the side. Good to know it’s all just part of the swoop dome.
