White smoke is blowing from exhaust. Is there some tests I can run or should I just go right to the head gaskets?

Guessing it's water, probably intake gaskets
Yes that’s what I was thinking as well but my oil smells like gas? It’s definitely the gaskets I think I’m just going to do them all next weekend. Don’t suppose you have any tips for a guy opening a gmc for the first time?
