Back in the days before we had friends with shops and garages, a friend of mine and I did a head gasket in my F155 fj40 years ago under a leaking tarp in a 3 day rainstorm. We literally sopped up water with t-shirts and rags from the cylinders berfore assembly.
Motor smoked like hell at start up, but ran for years of abuse after. We were both surprised.
You should be fine.
