Deck height
on the bore my guess is there is some carbon up above the top ring and your getting fouled by some carbon buildup.
FYI the felpro and victor gaskets are the same, Madmax runs a felpro at 12.5:1 in the mid 11's...
as far as the gaskets go they make both standard bore and the .110 over in all three brands, even seen a couple .060 overs.
