The Doug's over the centerlink headers are the nicest street headers that I ever used in a SB A body. They fit well, have great clearance and have fat flanges . They are not cheap and cost extra to have coated but IF I ever do a street A body that's what I'd use. Can't argue that factory hp manifolds aren't a good choice either. But at this point a decent set of early ones cost almost as much as the Doug's!
