With "REAL" engines (i.e., not those for a sewing machine, like our GY6's!) the head gasket has coppy rings around each cylinder that crush when installed for a good fit.
The head gasket for the GY6 is just a black plastic thing. I don't see that anything 'crushes'.
Thinking about pulling the head off (for the 5th time on this ridiculous, keystone cops BBK install!) so I can lap the new intake valve in (which I plumb forgot to do).
But will I be able to re-use the same head gasket? It has zero miles on it, but HAS been used while trying to resolve the 'stuttering' problem I've had.
Anyone know?

These head gaskets are not meant to be reusable, once the head is pulled, the gasket should be replaced.
If you torqued the head down, better safe than sorry, replace it.

Todd is correct, the gasket does distort just like on the "real" engines you mentioned when they are torqued down. They will lose the seal if reused and it may seem to run OK if you're lucky but you will lose some degree of performance and burn some oil. It's not worth it, replace it.
