LA 318 compression numbers

Friend of mine has a 1981 dodge power ram 150 with what i believe is a 318, but it could be a 360.. I have not looked for any numbers on it.
It's got a tiny little 1 barrell carburetor on it. It's got a ton of starnge smog and emissions stuff on it. Anyways it was running really rough and he brought it to me to look at.
First thing i did was a compression test on it, Every cylinder on the drivers side was at 100 psi, this is cranking for 5 seconds with the gas pedal to the floor and with the engine warm. I found 2 fouled plugs on the drivers side, plug number 3 and plug number 7. Passenger side cylinder number 2 read 95 psi of compression and cylinder 6 read 95 psi compression and the rest were at 100 psi. Cylinder 2 and cylinder 4's plugs were fouled. And cylinder 8's plug was oil fouled.
So it was only running on 4 cylinders. And his plug wires are junk and all taped up. But anyways we are at 4000 feet above sea level, are these compression numbers good or bad? What kind of shape is this engine in compression wise?
My 360 magnum has 150 psi on every cylinder at 4000 feet above sea level, so his numbers are down compared to mine, but i dont know if they are horrible numbers or not?
