Yeah, for sure all G60s are Hydro,
but there would be no real benefit to using an aftermarket MLS gasket for a G60 as opposed to a MLS from an AAZ. (if you have to plug the head for both)
It can only cost more, and probably be not as well built.
But, if they were to fit right up....
I can get my hands on a new one of each, and compare,
but I cannot return it once I have cut the package, which means I am keeping one of them.
But again, I keep expecting someone to say
"no, I thought that too, but then I looked..."
