No valve adjustment?

This isn't a Pep Boys or anything. This guy runs a small classic car shop. I talked with him about my car for over an hour today and he was VERY knowledgeable about the slant six. He knew lots of small things about the car and the motor and I didn't even have it up there with me. He runs it by himself and was more than willing to let me tinker with the motor by myself in his shop space. Me being the police didn't hurt either!
