Round Port Stock Exhaust Manifold??? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a SBC 350 with round port heads on it. I would like to run a stock style exhaust manifold because the headers I have are a pain. Does anyone know if GM produced a "ram's horn" style exhaust manifold with round ports that might work?

Are there any passenger car applications that might work?

Any ideas on what would happen if I ran the stock manifolds with the round port heads?
