I discovered that same problem when I installed my Brembos last spring - I'm surprised no one mentioned it ever.
What I did to solve it was use the left caliper on the right side and right on the left side. This way the flange on the calipers was orientated on the top and the brake line banjo block's flat top part would sit flush against it same as with the stock calipers.
But to swap the caliper sides I had to remove the bleeder screws and cross port tube and swap them to opposite ends so the bleeders were on top and cross port tubes on bottom because they were upside down after switching the calipers for opposite sides. Thanks to that external cross port tube design you can do that. Grinding the brake line block down some is probably easier but this way was quick and it worked out fine. I've since learned that SRTs use different brake lines (at least on the rear) which is why this is an issue on non-SRT installations.
This is a pic of the left rear caliper (which is supposed to be for the right side) so you guys know what I mean. There is a flange on the top of the caliper where the brake line block connects. The block has a rounded side and that is what interferes with the caliper flange if the other caliper was mounted there the flange would be on the bottom of the block and interfere with the rounded portion of the block.
