I can't figure it out, maybe you can?

If it were me, first I'd check my (new) rocker arms, lifters, pushrods & make sure THEY didn't break, bind, whatever. Assuming they're all good, I'd re-set ALL my valves to make sure nothing else got damaged/broke. Putting the original spark box back (since it was functioning prior to this) wouldn't hurt either.
The reason I say all this is, I seem to rememebr a story of a guy who had a Max-wedge engine and floated the valves on it so badly he couln't start it. Thinking the motor blew he simply sold the car with a "broken engine". Some guy bought it & while going through stuff prior to tearing it down found the timing chain had skipped a few teeth causing the whole valvetrain to be out of whack. I'm thinking something similiar is going on here and just needs to be re-set.......
