Weird Hemi Header set up

The pictures of those NASCAR Max Wedge Tri-Y headers are the ones that the owner sent me decades ago, as at that time i purchased the single left side one that he had for sale, back then.
Had the left side one for decades, before i sold it off.
It went back East somewhere, and then changed owners numerous times throughout the years, back then.

Ya, i would agree, a pair of them are pretty heavy.

At one time i used that single manifold as a door stop, believe it or not.
