Big Block Doug's Full Length Headers

Slickfish66 · Aug 30, 2025

Does anyone have any experience with Doug's headers with big block on 68 to 69 Road Runner as far as Fitment and quality of the headers I'm looking at the full length ceramic coated polished set, any information would be appreciated greatly.

Thanks Slickfish

T T I is the best for fit on a mopar. hookers were good but you would need to remove header to replace starter on the T T I i loosen bolts and the stsrter will slide out if you use the mini starter it might slide out with the header tight.

We installed Dougs on a 68 coronet 440 with no problem. A 383 car should have more room yet.
