Thorley 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?
