Default head gasket help for an L92 setup

Got a 427 (or 429 if you do the math) based off the L92. My builder sold me stock L92 gaskets for the 6.2L engine. Based off my math, being that the 6.2L is stock with a 4.065" bore, the stock style gaskets won't work well with a 4.080" bore. Is this correct?

GM Part number 12610046 was spec'd and shipped to me for use.

Is this a long 4.1" stroke .020 over?
I would really call the builder as it is his call.

Well, the heads and short-block are all sourced from the same vendor. When purchasing and doing the final parts tally, I asked for head gaskets. These are what were sold to me, so I'm guessing that was the recommendation. I'm just double checking as I'm not sold on it after doing the math.

You can use a 4.130 without any dramas at all . That was what was recomended for mine and it's a 4.0 bore fit was perfect.
