John,
Didn't realize you were looking to use oversize pistons. If the deck
height remains the same, you will not raise the compression enough to
worry about it. I think the cost of the special pistons and rings will
be prohibitive though.

I realize larger pistons with matching rings would be required. I'm
concerned about what the increased compression will do in  terms of
additional heat generated.

I'm pretty easy on the machinery, but some things that are induced by
alterations could be destructive, or could shorten the live of the
engine
and may be beyond my control.
