Well you don't want them to loose. then they won't open enought and you'll get lose of power that way. the valve has to open a certain amount. like if you put a dif cam. it might open the valve more, or longer sometimes both. but if you have them adjusted to "loose, sloppy" then it still won't run "right" and might click and rattle.
so this morning when you got 200 psi. did it not start again? i'dd pull the plug and crank it for a few to blow any excess gass out and give it a new plug and see if it fires then.

Without the valves adjusted the compression number don't mean much. Besides that his compression gage may read high. He need's to adjust the valves before he does anything else. And I hope to hell he didn't try to start the engine without the valves adjusted.
