Lumbergh, I've done worse. I neglected to say that you needed to watch the valves on #1. I've never been able to hold one finger on the sparkplug hole and crank the engine over with the other hand. I don't really watch for both valves to closed. I'm more concerned with the sequence. When the exhaust valve is closed, it's done with the exhaust cycle. The next stroke is intake. When the intake valve starts to close, I start looking for the timing mark on the crank pulley. If I have any question about how close the timing mark is I've got and old sparkplug that I've knocked the insulator out of and replaced with threaded rod. It's really what ever works for you, as long as you know the basics, then you arn't going to get hurt too bad. btw I just picked up a shop manual for 58 Chevy trucks. There is a real interesting section on how to check your motors power balance. All very logical just never thought about it. It's late I'd better quit before I screw up.
