73 - 454 Exhaust Manifolds
I have Dorman BBC exhaust manifolds # 5013905 and 5013906. It seems the rt side is ok but the flair on the left or drivers side is not correct and interferes with the steering box.
Any ideas if these manifolds are for a 454 or maybe a 427??

They must be casting numbers or ????
DORMAN 674506 {#3969923} (LH), DORMAN 674505 {#3880834} (RH) are the part numbers they list.
I ran a set of the "427" stock manifolds on my 72 454 without any issues, tight near the steering but not a lot different in that area really
