On the left side it was a little closer, but it will work there too.
Maybe there will be a 1/16" at the top corner of the mount that interferes with the header tube, but I can live with trimming or dimpling to make that work. As it sits mocked up it isn't touching but it's feeler gauge close to the metal flange.
The pics make it look tighter than it really is.

Also, there must be a slight difference in the block webbing between the 6.0 and car 5.7. There are tabs on the back side of the mounts that you have to bend flat for these to fit right side up. They will go on upside down no problem, but not right side up. I had heard mention of this once, but just wanted to throw it out there for anyone else. Maybe it's different for OEM mounts also, these are re-pops.
