As I said, I have no knowledge of what you've done to the car, but it did come with a cat on it, so I wanted to cover that remote possibility.
If you adjust the valves running, like the chevy procedure, back them off until they clatter, turn them down until quiet, than add 1/4 turn you'll be in the ball park, and can eliminate valve adjustment as the cause. Yes it's messy, but it is effective, and very simple, and quick. You can then go back and adjust the valves any way you feel is the best way, but it quickly gets valve adjustment out of the way as being a problem. Getting stuck on how is the very best method of adjsting valves is incosequential when you're troubleshooting an engine problem, do it the simplest way, and move on.
Getting stuck of turning the pushrod between your fingers, while making sure the lifter is on the heel of the cam is a little involved for troubleshooting a problem. You can go back, and redo the valves later if you feel the need to.
Make sure the secondary metering rod/rods haven't fallen out of the hanger too, another easy to check problem that I've seen happen. Also when stripping an engine down, and disturbing a Q jet, if it has sediment in the bowls, you can redistribute the sediment to clog an orifice(s) and screw up part of the circuits in the carb.
Then you're back to firing order, or cam timing.
