Help Understanding Leakdown Results

Those numbers are a lot better than the last set you posted.
That being said, where is the air leaking? Do you get air movement out of the crankcase?
Intake?
exhaust?
If you have some leakage at the valves, then replacing a head gasket should include at least lapping them while it is off. I'm not trying to instigate mission creep, but that is a really good time to check them if you suspect them.

 

Since the jeep sat for a while I have no clue why it wasn’t being used. I have to assume the engine was giving the owner a problem. I think the air was escaping through exhaust valves—just a guess. I’ll know better when I pull the head. Might as well do things right. Unless I spot something really amiss in the lower end, the engine shouldn’t need a rebuild. Lap the valves, new head gasket and call it good. I suppose the worst thing would be crack between 3 and 4. Fingers crossed it’s not that.

 

It's a slippery slope. Often it's hard to to avoid one thing justifying another, and then it's a financial rabbit hole.
