Did a compression test........
.... yeah, did a compression test on teh pass. side of the truck.. The back two cylinders(looking at the engine) are a whole 25PSI lower than the front one and the other side. THe other four are at 125PSI and the two are at 100 PSI..
This sucks so bad, I dont even know what to do right now lol.. Anyone got any advise?

Don't panic yet...you did a compression test and 2 cylinders are low...ok. Now, do a leak down test to determine if it's the cylinder rings or the valves leaking.
--It could simply be a stuck valve or a valve that's bent (I hope not).
--It could be a stuck lifter because it's not uncommon on a OHC engine.
--Are there any tapping noises? Put your ear up to the valve cover with a wooden or metal bar and listen to the valve cover for any noises.
--Did you take off the valve covers to see if anything looks wrong?
--Look at the cam lobes, it's unlikely but it does happen.
Does the vehicle feel low on power? If not, maybe you did the test wrong (again, it does happen cause those cylinders are hard to reach).

Take it apart and wait to see what's wrong with it before you buy anything. My guess is something with your exhaust valves.

Well, im in germany and in the military, so, #1, parts take ATLEAST a week to get here, and #2, taking time off isnt that easy, so i cant just take time off on a whim like that. idont see how it couldnt be a coolant leak.. My coolant is dissapearing somwhere, and there is no leak in the hoses, or in the radiator..

sorry rangerdad. and the two plugs on those two cylinders, well there is something wrong. the threads are COVERED In something, not sure what and the actual electodes look like they have been in the engine for a lot longer than 3K miles.. The other plugs have clear threads and the electrodes look nothing like that.

buy a head gasket from a parts store, the price shouldn't be much more than jc whitney's parts... it was like $50 for 2 of them for my mustang the left and right banks are NOT the same, so make sure you get one of each, the head bolts, depending on the type of bolts they are, you might need to replace them, the ones you have to replace are torque-yeild bolts, i forget the actual difference between them... something like you torque it to spec, then give it 3/4 of a turn more and there is a section of the bolt that stretches... i don't think ford ever used them though...
