I know a lot of discussion has been done about this but I couldnt find much definate into which ones will fit and which ones will not and why.

The swap headers that Schoenfeld Headers makes are very nice and fit well after they re-designed them.

But what about the Camaro longtube headers that are sold on eBay or the Pace Setter brand headers for a Camaro or even a 99-Up NBS truck; will they work? If not what do they interfere with?

I even thought about shortie swap headers but didnt know if they interfere with much on this body style either.
