Header recommendation, 1968 Dodge Dart, 340 4speed

its been proven orig hipo 68 to 70 manifolds flow just as good as any header.
and they never leak.
cant use headers in the F.A.S.T class

And every one of those guys would rather have a header on the car when chasing ET

The 68-70 manifolds don't work as well as a long tube header and that's been proven for many years.
