Well I would do the compression check first without the need for getting it running. Running and then doing the test is better (but not by much), but on an engine out of the vehicle, you know nothing about it. Adjust the valves and then do the compression test. Maybe you will find out then why it won't start. I would put a good heat lamp or two on the engine and try to get it nice and warm, or if possible let it sit in the midday sun. Then crank it and hope for the best. Better add this - since the valve cover is off might as well oil the cam shaft before cranking it over. Oil is cheap and it can only help with your compression test, so oil it up.
