These rings are not just a ring. They are engineered and have features built into the ring that grip the iron and Aluminum head. They have a top and bottom. It took us a year to get this designed so it even could be machined.

Just think you order your block with this sealing option and your done. The block is dry decked from the factory. So no other machine shop work need to the deck surface.
