440 manifolds questions

[1968Charger27]

Looking for a little info on what these numbers mean? Put headers on my 68 charger. 440. I plan on selling them and trying to find a price as ebay has them in a wide range of prices. Thanks for any info.

Those are Year One reproductions. As far as value maybe $400ish?? Others will probably know the value more than I do.

Yep. Find out what year one charges, plus shipping, and ask for about 2/3, plus shipping.
Frankly, I'd keep em. You may get tired of the headers some day, or you may decide to sell the car, and the buyer might not want headers.

Just the info I was looking for. Thank you
