Hi all, i just wanted to post a thumbs up for the headers that just went on my '70 coronet, I ordered a set of Summit Racing 1 7/8 ceramic coated big block headers for my 500" low deck with a stock k frame, manual steering , column shift auto and 440source stealth heads and they fit better than the 1 3/4 headers that were on before. These headers required zero mods and plug access is excellent, the person who installed them has been working on fast mopars for a long time and told me they are the nicest b body headers he has seen. all that and they are less than $400 so i thought i would post incase anybody was thinking of buying new headers soon. PS the instructions that came with them are from Patriot Headers so i guess Summit just rebrands them. have a nice day all.
