Which Headers ?

Wouldn't original or even reproduction factory style exhaust manifolds with the 2 1/2 inch diameter outlet look, fit, flow, as well or better than the Speedway rams horn headers? They were good enough for the hi-performance Corvettes.

Still allowed and used in Stock drag racing classes, and for most engines with relatively mild cams they flow just about as well at normal operating RPM.
