Well you don't know if the the head will fix it #1 and they are different. the leakdown check can tell you if it's valves or rings, when you put the air to it, if you hear the hissing coming from the intake or exhaust, it's the appropriate valve, if it's coming from the oil filler, it's the rings.

You could get away with just a simple valve job, or a hone and set of rings. if it was me... well....been there done that.
