Alright, thanks for the input. This is the engine that came in the truck when we bought it. We origionally thought it was bone stock, but once we removed the right valve cover we noticed the heads were extremely clean so we know atleast those may have been rebuilt. Anyhow, the #4 INTAKE rocker stud was pulled, AND the #4 EXHAUST cam lobe was wiped the first time we removed the valve cover. Just for the record, we did get the #4 intake stud fixed, no more pulling. We got it running rather decently today, and plan to drive it out to my shop where it will sit until the new engine is done. I really don't care what happens to this one, heck I believe a main bearing is bad anyhow, considering what I could hear before this fiasco. Thanks everyone, here's to the biggest PITA ever.
Btw thanks for the link Doc, that'll do.
