Are you sure it was the head gasket and not the belly pan gasket under the intake ?

Slvr,
Thats possible, the more forceful fuel/air explosion -could- cause that I suppose. It depends on what the final octane ended up being, if you were running premium and poured that in, and for some reason your truck was detonating (pinging), then yeah, I suppose it could.
Also possible is that you overrevved and the compression blew it out, or a combination of the two. Since your going to have the head off, have them check to see if it's got a clean mating surface with the block. It's possible that the surface wasn't perfect, and when you got on it, the gasket let loose at the weakest point.

Octane will not blow head gaskets. I'm with Dan... If you have a blown head gasket then as your taking it apart get a close look at the intake belly pan gasket.
And the only thing that will happen if you over rev is stretch your rods, crack a piston skirt, or float the valves (My personal fav)
Good luck
