I made the mistake of trying to use a set of the original Pro Part headers on my 1969 383 Dart GTS 4 speed car they where not designed to be used on low decks in A bodys High deck motors only I'm not sure about the new ones Mazolini is selling now



I thought you could use the proparts on a low deck with -1 heads like prosport does ... I have the new 2 1/8th in proparts with RB and -1 heads I needed a couple tubes fabbed for clearance but looks nice now cause of the ceramic coating
