After I added the dual exhaust and Fentons, I put it bake together with a new spacer and no gaskets. Ran O.K., but definately had that popping and spitting sound when decelerating. My neighbor is a great mechanic and fixed it for me by adding the gaskets. He also fixed my sticky linkage that I didn't get right.
But here's where the story gets interesting. He was having a heart attack while finishing it. When he was finished, he figured something wasn't right and called the ambulance which saved his life. That was a year ago last September. Now he eats a better food and is 60 pounds lighter. What do you do for a guy who just about kills himself working on your truck?
