Called flotech, nope won't work. He called Sanderson, said maybe. Called Sanderson they said nope, problem is center dump plug clearance.

Still on the hunt for a solution, wonder if I could make a transitional spacer 1/2" aluminum

I have ran headers with my vortecs since they started making them. I don't get leaks and my bolts stay tight. A ole street racer buddy told me the trick a long time ago. When the headers are welded it warps the flange that bolts to the head. Remove the headers and cut through the flange on each side of the two center tubes. Get you some stock manifold gaskets (metal) and forget about em.

The issue if I remember correctly is that the spark plug location is different on Vortec heads. Great for power but will put spark plugs 3, 4, 5, and 6 close to the ram horn manifold as stated above. So close that I believe you'll be burning up spark plug wires.
