Why should there be a difference?
I’d never deal with a company that says ohhh sorry if you want ones that fit you have to pay more. Otherwise you’re stuck with our crappy fitting, linkage must travel through, hard as heck to install, guaranteed to rust, will totally melt your spark plug wire boots, low hanging crap….
I agree with anyone who says Hooker headers suck for mopar. If you’re going to make a header, make one that fits.
