Thorley Headers

[urdustd]

I bought a set of Doug Thorley Headers a few years back on E-bag. I need some help identifying if they will work on my Duster.

The car is a 74 Duster 360, floor auto, E-heads, PS and PB.

The headers came in a Doug Thorley box and the flanges have "52" stamped in them. They look very similar to a TTI's except the #3 tube on drivers side is straight down, not curved to the rear of the engine compartment. Checkout the pics below.

Has anyone seen these before? Has anyone used them in an a-body?

Thanks for your help

Would they also be referred to as Dougs Headers. If so i've heard some good stuff about em. Never heard the Thorly name though. They don't look coated. Don't look beat up. Hard to say what they would fit. What did the previous owner tell ya they would fit? Any numbers on em anywhere? Are ya going to use em or sell em?

Yes those look like Doug Thorleys..they're not Dougs big difference in the 2 headers...

They are not Doug's headers. They are suppose to fit small block Mopars and possibly only b and e-bodies. I can't find any documentation on them. I'm still a little undecided as to whether I will use them as I would really like them ceramic coated (figure an extra $200+). Again they are suppose to be p/n 52. By the way 1 5/8" primaries and 2.5" collector. Another reason I might go to Doug's or TTI's.

Has anybody used these before?

When Doug Thorley got divorced, his wife took over the company. Doug came back and opened Doug's Headers (which is now owned by PerTronix). He was smart to have the tag line: "The Original Doug's Headers".
