Corvette White Smoke Out Exhaust

My Corvette ran fine when I brought it home. I drove it around and got on it to see how it was. When I got home the coolant was bubbling out the radiator cap. The fan wasnt kicking on so I wired it straight to the battery to make sure the fan motor was good and it was. I filled the radiator up and drove it down the road and back. The engine was clearly overheating and I seen coolant bubbling out what looked like the valve cover but the header was right there where it was coming out so it could of been coming out there. The car had lots of white smoke coming out the exhaust except when I would rev the engine up it would stop and after it idleing a few minutes it would smoke again. This was not from condensation in the pipes this was a alot of white smoke that smelled funny. I think its a blown head gasket but want to ask around before assuming anything. Any advise on what it is.

Thanks guys

Coolant bubbling out of the valve cover??

If you don't see any coolant coming out of a crack somewhere, I would suggest a head gasket, maybe warped the head if you ran it hot, especially if aluminum, although it would be coming out below the headers, where the head meets the block, somewhere around the head mating surface. Do a compression test.
