which year Camaro?
I think you square body guys have more room in between the rails than my 66 does, but even so fbody headers might be a bit of a squeeze. Trailblazer SS stock manifolds fit easier than almost anything else, but if you want longtubes the Dough Thorley is a preferred but PRICEY option.

You may try gen5 Camaro headers, as there have been some recent posts on them fitting well (the stock ones that is).

Fitment can be different even on two of the same year trucks, since the front->back positioning is different based on which mounts, which position etc the engine is in.
