Well, I know DSE headers work with my setup. Their headers work with both size body mounts and you have to use different engine mounts which sets the engine back an inch and a half. Dan checking on another set of headers and I'll post pics of them when they are ready.

Good luck finding something that works for you. This is the reason I'll most likely make my own.

Are you set on SS? Dynatech also has a header available but they aren't stainless http://www.dynatechheaders.com/m_camaro_67_69.html Again, no idea if they'll fit the DSE subframe.

Have you considered having a custom set made? This might be an option for you. I'm not sure on costs but the idea sounds pretty cool. http://www.icengineworks.com/

Customs headers would be cool. Going to try a new set from RS. Dan said they shoud do the trick.
