Small block headers: worst to best fitting. List your experience.

The 5303 had the #1 tube go straight down thru the "Y" gap in the k-frame, then went under the k and steering gear.
Was first header I bought for the Dart from the Mopar Parts counter, kept warranty too.

No, you didn’t have a set of 5303 Hookers.

You had the 5204 header which is a street header.

I never had a set of them that didn’t fit and fit well.
