I never said thank you, Chad. Sorry about that.
Appreciate your reply.

Since then, the truck became one of those "Well, since I'm here I might as well do that. And that. And that..."

So, did a full top end seal and gasket replace, water pump, belts, etc.

Due to the inevitable detours of life, I'm happy to say I finally started it up yesterday.
Troubleshooting continues, but if that ain't the sweetest moment after tearing something apart, I don't know what is.

Number 6 isn't firing, so have to tear it down a bit again and see whats what. Narrowed it down to the injector as a possibility.
They look original. My gut told me to replace when all was exposed, but oh well. Learnin...sometimes the hard way.

This is DIY...This is the Way...
