I definitely would do a leak down before tearing into the motor. It shouldn't take TOO much air to do leak down i wouldn't think? Oh well none the less do you see anything that seems off? Did you take just the valve cover off or the entire cylinder head? I am going to assume you took just the valve cover.

I wouldnt replace the head until we know exactly what is leaking. Once we know for sure what is wrong we can make decisions based off that evidence. It would suck terribly to replace the head just to find out there is a crack in your block that is allowing compression to not exist.

If you can try that leak down and lets find out where the air is going.

Cheers!
