Case closed...
I was looking too deep into it. I had a crack in some plug wires and I was getting spark jump to the exhaust manifold.[sm=bangbang.gif]
Head replacemnet was a success. THE TRUCK FINALLY RUNS GREAT!

Wow, a visit to an old post.
The problem turned out to be a warped head, which I hear is a somewhat common issue with trucks from this era. I replaced the head and everything was fine.
