I have a 73 with a BB and I used the Hooker Comps they fit great and were not expensive $150. They do have 2" tubes. I am very pleased with the fit. However, you MUST use the BB Motor mounts for them to clear the steering box.

Aren't those the Hooker Super Comps?? Hooker has several lines and I think the Super Comps are the best header for the money.Toms73NovaSS said:I have a 73 with a BB and I used the Hooker Comps ...
Actually, Tom, that's a '68-74 in the pic. They all have rear steer.Tom Mobley said:thanks for posting that pic. that's an early type rear-steer car, many headers have issues around the steering box.

No street clerance problems, Both are same height and tuck up under well. Actually better than the headers I had on the 350 before the 454.Tom Mobley said:thanks for posting that pic. that's an early type rear-steer car, many headers have issues around the steering box. Those look pretty good to me. Any problems with ground clearance? I have a set of the cheap hookers on my Chevelle,eveything is cool as far as fit, but the drivers side header hangs down almost an inch and a half lower than the passenger side, always scraping the collector on the street. I'n so tired of it I've gone out and bought a different set.
