Can anyone advise on a 2008 challenger 6.1 that has aftermarket headers now, if I need new bolts or studs to replace them with the factory exhaust manifolds or can I reuse what appears to be bolts holding headers on now.
Also do I need to raise the engine to replace the headers, Thanks

What kind of headers are on it now?

Chances are you will need the factory hardware to install factory shorty headers, it really depends on what the flange thickness difference is between the current headers and factory.

Not sure what kind, just picked up the car , former owner, unknown, has sure put a lot of money in the exhaust but want to put it back to stock, has exhaust cel coming on from time to time, common problem from what I hear, don't think they were worth it over factory, located factory manifolds, now guess I need, like you said a complete bolt set, Thanks
