ECE Motor Mounts + Gen III = ???? Headers

[SCIV]

OK, I have searched , but want to know if there is anyone with ECE mounts, 6.0L motor (or other models) that are running headers? I was looking for specific brands.

I know the factory mani's will fit with trimming, but I am going to run headers while I sort the swap/suspension out before going to twin turbos. I see '99-'02 f-body headers seem to work, but I was looking for someone with the same setup as me with actual hands-on experience!

Thanks in advance!
