Sorry, I was off in my interpretation. 400 is excellent, 300 is passable, 200 is about the minimum to start the engine. I would think at 240 psi it would be impossible to start this engine for all but 3 months of the year in Michigan. Conversely, if the engine starts easily, something's wrong with the compression test, not the engine. A compression test is a diagnostic step, not preventive maintenance.

Valves should be adjusted, or more accurately, valve lash should be checked every 15K miles. No questions, don't wait for symptoms, just do it. Check timing chain elongation while the valve cover is off.
