Thanks Gearhead,
I have a friend that wants this van...
... so maybe I'll just go ahead and sell it to him and get myself another 1971 to 1977 Dodge Van instead.
Blessings!

You're welcome. But interestingly, the Summit Racing tech indicated that headers for this age of vehicle are not as beneficial as the older muscle car era vehicles. I'm not sure if it's true but it would seem like he is in a position to know these things. Also, have you seen the Ram Van racing vans in Japan? If not, take a look on YouTube. They run 5.9's maybe you can make a contact in that world. Who knows maybe there's a Japanese header vendor. Apparently there are about 50 race vans!

 

Here is a link to one of the videos.

 

I would think these would fit, but message the sellers to confirm.
