Aluminum 'Press In Sleeve' block warning
This is to make the forum aware of an issue present with Press In sleeves as used in re-sleeved LS2,7, Warhawk and RHS engine blocks.
The use of an improvised cylinder ring (that uses no machined receiver grove) or a gas expandable ring as used by some head gasket companies can cause unwarranted effects to the 'press in' cylinder sleeves causing them to be pressed into the block and below the deck surface, potentially damaging the seating surface for the sleeves.
Traditional O ring with a receiver grove using a copper or graphite gasket has proven to be satisfactory, provided the depths of the groves are done properly.

The block was purchased that way. It originally was going to used with a copper HG. Was told it could be used with an MLS as well. What issue do you see?

You could I suppose torque plate hone the block with the ring and gasket installed, good luck with that.
