Since all the cylinders will be sleeved, the ring position won't matter. The sleeves will project up into the adapter plate about 1/4", making the surface smooth all the way to the intersection with the adapter. There will be a copper sealing ring between the top of the sleeve and the plate, similar to how the cylinder on an air cooled Volkswagen engine mates to the head. All the Atlas head gasket will do is seal compression and coolant at the top of the adapter plate. Coolant will be routed from the block to the head via external fittings- - - -no coolant flow through the adapter plate. Jerry
