If you are running a mild engine you won't really gain anything by switching to block huggers if you already have the old rams horn style manifolds. If your engine is that mild, I wouldn't use anything over 2 inch exhaust on a small block. It will actually hurt engine performance. I have a mild 454 and only use 2.5 inch dual exhaust. I am assuming you want to use block huggers for the appearance. I would get them ceramic coated, not sure what manufacturer makes the best. I have Hedman long tubes on the 454 and have had good luck with them.
