These headers came with a 318 cored I picked up. They weren't on the motor, but they look like they might fit. They do however look completely different compared to headers I had on another motor at one time. The "straight" pipe crossing from back to front has been made removable and the collector flanges are square.
Dang......it's been 44 years since I had that car, so I can't remember to save me! I wanna say no 90 degree adapter needed, but I'm not sure. Do you have a spare engine laying around that you could mock the passenger side header to and find out?
