The tri-y's, If you set them atop of a known set of A-body headers are they the same size or taller? I'm Looking into a set of headers for my Ramcharger. Is there any part #'s on them?
The tri wyes seem to be an inch longer from top of flange to bottom of collector. They also do NOT hug the block as all the others do. They look like JBA or thorley. JBA doesn't offer this anymore. I found a pic on a Mopar tuck forum that shows these. The flange is deep enough to block smog ports.
