Anybody Remember the Mickey Thompson Super Scavenger Headers!
Now I,m reasonably sure the main idea was more towards ease of manufacture and low cost, than any effort at making a true race header and the squared off , overly long collectors were not well received , by the public if my memories are good.
the basic idea was that each primary tube could be cut to the same length ,but not necessarily end at the same point in the collector, this allowed you to use the slightly rectangular tube that functioned as a collector to enclose the ends and even if each header primary tube ended at a different point in the collector it still made welding the header fairly easy.
now the strange thing is that these headers actually DID run rather well
(better than many people would believe in fact)
and in fact allowed the engines to produce very good hp,
I remember my 1965 LEMANS that Id installed a 496 BIG BLOCK CHEVY engine in, ran rather well with those headers.

I came across a very old set that had obviously been sitting neglected for decades in the back of a garage,I purchased them at a local yard sale,
(this is a picture I found on the internet of similar headers)
I picked those yard sale headers up for $10 just to clean up and hang on the shop wall as a decoration after I bead blast and repaint them of course
