sounds like since u did the valves wrong the first time the pistons might have touched one or more and bent them. Would explain the power surging, inability to keep an idle bc of vacuum/lack of air. And the typewriter sound could be a loose valve.

Best case scenario is that one of the rockers came loose bc of the lack of tightening which would cause the valve not to move at all and cause the same issues ur having. Plus the rocker bouncing around would make the ticking sound.

You really just need to open the top up again and take a look. Also if you dont see anything wrong go pick up a rental compression tester at an auto zone and test for compression to see if its good. This will tell if you have a bent valve
