4.190" headgasket okay with a 4.155" bore? I am about to put my engine back together once I get the bearings and gaskets. My initial setup had 4.165" head gaskets on my 4.155" bore block (434ci) and I was told that ill be receiving 4.190" head gaskets this time around. Will I run into any issues running head gaskets this size? The engine will see some nitrous.(150-250 shot)

Yea, no problem. Keep in mind most OEM GM gaskets run a good bit larger than the bore size they are being run on.

Ask your engine builder what the compressed thickness of your new gasket is compared to your old gasket. This can effect your compression ratio.
Also, where is your piston deck when the engine is cold? Is it above the block, equal to the block, or below the block?
