Spark plug stuck so I have a BIG questions (gaping)
I was able to remove 3 out of 4 spark plugs to check gapping. The 4th one was stuck so I could not pull and check.
The 3 I removed where gapped to .042 so I regapped them to .044, but the 4th spark plug is still in there and I assume its gapped .042 instead of .044
So my question is, will I do any damaged running 3 gapped at 0.044 and one at 0.042?
I dont want to force out and strip head so I'm leaving it in there.
I really appreciate any help I get

DO IT ON ALL FOURS

No, .002" isn't going to make a bit of difference on a stock vehicle let alone a mild/moderately modified vehicle.
Spray penetrating oil down your spark plug tube and let it soak. You can do it right after its warm and let it soak for a while. If you get it broke loose, you can work it back and forth slowly. Loosen it a little bit then tighten it back, then repeat but loosening it a little more each time... add prenetration oil as needed.

I want to try that. But i dont know if its stuck cause it needs some pb blast or if whomever worked on it stripped it?

Its gotta come out eventually.
Was the car warm when you tried pulling it? If not, give that a shot. Aluminum expands when hot, so you should always remove plugs from a warm engine.
As mentioned, PB Blaster is amazing stuff. A good soak will likely break it loose.
IF, after a soak in PB, and warming the engine, it still wont budge, its time to start thinking about Plan B. You are either going to have to force it out, and hope for the best, but prepare for the worst. Be prepared for, at worst, having it removed and the head worked.
But I would almost guess that if you try some PB and a warm engine, it will come out OK.
