Early A with 360/power brakes

So the difference I am seeing in my setup versus the ones that are being posted is the MP magnum valve covers are wider (and possibly taller?) than the LA valve covers.

The brake booster setup I have is like the one that Moparlee posted. I am thinking my options are to either scrap the power brakes idea (not my favorite), modify the mounting brackets for the booster to sit 2 inches higher (will still clear hood but with change the angle of the rod to the pedal), go hydraulic, or try different valve covers(using Indy magnum X heads), comments on the various options?

What about a hemi offset booster bracket?
