Headers with four bolt collectors ends???

[rikubot]

I've got the chance to get some used BB headers from a friend for about $80. They have some black coating that supposedly doesn't burn off. They are a little beat up but not too bad and the collectors have a four bolt plate. Never seen that before. Not sure if brand and I can get pictures. Any thoughts or info is appreciated.

not sure on what brand had them but IIRC they would be an older design from the 70s? Most headers nowadays have gone to the "standard" 3 bolt triangular pattern.

max wedge manifolds have 4 bolt square pads I believe - maybe a replacement header ?

Appliance headers had 4 bolt collectors
