We got the light on the scope to work and got a pretty good look at the valves. The exhaust valve looks like it has a flat spot on the edge of it. Just for the hell of it we did a dry compression test on all cylinders.

#1 105 psi

#2 115 psi

#3 110 Psi

#4 115 psi

#5 105 psi

#6 110 psi

#7 120 psi

#8 15 psi

I'm not real interested in dumping more money into this truck right now so I'm not sure what I'll do with it.

Next step is to pull the head. Period. Take it down to the shop and have em check the valve.
