Deglaze and reuse rings?

Never put rings back in a cylinder once they are removed. You will never get them positioned/clocked where they were. So you will have additional wear to reseat them. cylinders change shape when they get warm. They do not stay round.

If you cut the block and the head you will have to check the intake hieght.

My son installs lnkanell wire in the head or block that pushes on th fire ring on steel ML gaskets. most all diesel motors for pulling are done this way at the shop. Or anything making alot of boost.
