My shop manual says that they should be at 130. I have no idea if the gauge is accurate or calibrated, I borrowed it from my uncle/cousin. However, if I remember correctly from math class 0x anything still equals 0. The manual also said that this is a sign of a head gasket leaking between the cylinders. I have a theory on how to test this, but have not run it past a real mechanic. If I put one of the plugs in a dead cylinder, and the one next to it builds some pressure, this would indicate a leak? Considering the rust problems, I guess it is safe to assume a bad head gasket. I went back to look at pictures, those were the dirtier plugs:

I am going to ask the local experts their opinions, but I am guessing I need to yank the motor and do a re-build. If I go that route, I may pull all the sheet metal for a real paint job. Not sure yet.
For now, I am goign to see if the motor will limp along enough for me to work on the brakes and other non motor moving parts. To that end, I took off the gas thank that was primarily used, and took it to a radiator shop for cleaning. Had some trouble finding someone with a big enough tank, but it is being cleaned as I type. With that back in place, I can at least back the truck over to the slab to have a stable jack stand base. I'll pull all of the wheel cylinders this weekend. Hopefully.
