I had nothing to compare them to but in the early 70's Mickey Thompson designed an equal length header where the tubes entered a collector/canister that formed a chamber. This way he did not have to have them look like a pile of spaghetti. The order in which they entered the collector/canister was also important as it affected the exhaust scavenging.

If you want lots of low end torque you can go as small as 1 5/8 primaries and 2 1/2 collector. Unless you are going all out you are better off under size than too big. I had a Roadrunner w/383 and a set of Headers by Ed and he insisted on using 1 5/8 primaries. Got lots of torque and many trophies with that car.

Not to mention the fact that the 4.7 is a small displacement motor, and not known for low RPM torque...it likes to rev...it needs to rev to make power, which means you'd want shorter headers anyway.
You are right. I'm still living in the past.

It will still work on a 383 Cuda.:wave:
