Just Confirming - Cometic Head Gasket Reusable??
My head gaskets have been on for about 2 months (about 1 hour of run time).
I can reuse them correct? Anything special I need to do or just drop the head right back on like I did before?

Copper spray for the win. Used to do it / re use the MLS when I was in Supra/7m engine game.

Yep - it is called bore notching by most folks. Can gain you 15-20 HP according to legend especially for smaller bore motors like the 454 and 489/496. Pretty easy to do when short block is torn down.
"unshrouding the valves" can also refer to taking some material off the sides of the combustion chambers around the valves, but you need to know what you are doing here. It's possible to get carried away and maybe hit water jackets, and the chambers should probably be cc'ed to make sure they all have the same volume afterwards. Lowers compression ratio too, so if you are trying to keep your CR at a certain level, can be detrimental.
