Re: vortec heads. headers or ram horns?
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.
