Fluid spraying out of #8, #6 cylinders

I am suspecting I have a head gasket problem, as my truck is losing coolant internally, and oil that leaked out (due to loose oil pan bolts that I just noticed, I think) over a couple days had noticeable coolant in it. I did a coolant pressure test, which was good. Then I tried to do a compression test, the first one I've done on this truck, but 8 and 6 were spraying fluid, I think fuel but it was really hard to tell. Could be coolant, but it was only those two cylinders.

Could this be due to stuck valves? I know the seals/guides need replacing as blue smoke comes out at start up, but could this cause fuel spraying all over the place?

Incidentally, I think the fuel/fluid messed up the gauge. I did #2 and #4, and both those came up with about 60psi, before and after squirting oil into the cylinder. After I did #6, the gauge stopped working.

Secondly, would worn guides/seals cause such a terrible reading? Or the head gasket? Im going to drain the oil as soon as I can to check it, but I have never seen white smoke. I did find the intake manifold bolts were a bit loose, but I dont think enough to cause these problems.

Ironically, I just finished putting the MadElectric New System in (best upgrade yet!), and my truck is running smoother and pulls stronger than ever. I was just getting ready to finally start work on sound when I found the leak
