What Exhaust Manifolds on the Square?

Hi all, I'm tired of the headers I have on my 78 C-20. 1978 C-20, 350, TH-400, 4.10. I am wanting to go to an set of exhaust manifolds. Has anyone used ram horm style manifolds on their square? Any clearance problems? Which manifolds flow the best? I know it might be a step back in performance, but I am tired of the leaks, etc. that these headers are prone to.

If it ain't broke, there is still probably room for improvement.

Speed costs money, how fast do you want to go?
