So its not the accessories and timing is good. I am really starting to think its the lifters. So what now? I could replace the camshaft and lifters. Not too pricey to do, but is time intensive. I assume I should also do the timing stuff while I am at it. On the other hand, I could just use lucas oil and run it next summer and see what happens. Part of me thinks that if I tear it down to the block again, I should just do an entire rebuild (like I should have the first time I tore it down!!! -> oh well, Ibought this truck to learn and boy am I learnin')

You may also consider pulling the rocker shafts and knock out the plug on one end and clean the sludge out of the shaft with a pan of diesel fuel and a gun bore brush flush with brake clean and install a new plug.
