Once again Hot Rod gets to the core issues. Valve cover is so easy to pull I just take it off when starting any engine that has set. Turn by hand and look. You would be amazed what you can see. Friend had hit his started just to bump engine around to set timing, now he has a bent push rod. One sticky valve was all it took. The valve is fine, a little oil and some tapping with a plastic mallet, and it was good to go. The push rod? Toast. With mechanical gauge, oil pressure can be tested with the dizzy out and an old big blade screw driver in a drill. Lets you see it come up to the rockers as well. Pull the plugs. Look at them. You put oil in the cylinders, good. Now do things logically. Turn it by hand. Look. I would bet you see the issue. If you see something not right. Then take action. Not too hard to put plugs back in. Not hard to adjust valves. No too hard to put the dizzy back in. Not too hard to time. Breaking some thing sucks. I know I have done it. We all have I would bet. Lots of smart people here. ask and see what they have to say. There are NO Dumb questions.
