baldybenny, good sage advice I rekon

Jerry, thats a very interesting yet very do-able idea. I thought very seriously about trying it but I've decided when time allows, I'm going to declare to the truck, "off with zee head"

After letting that #2 intake valve soak for a couple days in daily applied PB Blaster it seems to have freed it up to where it opens all the way without having to force it.
As a last test, I dug out my radiator pressure tester and pumped the cooling system up to 10 psi and surprisingly, after I tighted up the leaking heater hoses, it held that pressure for over 15 minutes! I kept checking around the plug holes on cylinders 5 & 6 and couldn't detect any air/coolant leakage.
I also filled cylinders 5 & 6 with 4 pumps of oil then reran the compression test, they still wouldn't pump up over 20 psi.
#2 cylinder wouldn't go over 40 psi either.
So when time time allows, I'm going to pull the head.
In studying it, looks like I'm going to need to pull the side cover and perhaps the oil pressure tube that appears to carry oil up from the crankcase to oil the rocker arm assembly.
Probably pull the manifolds before the pull also.
