Just how ridiculous would this be?

Hello everybody,
I am finishing the very last stages of the 2001 360 thats going in my 78 cordoba. I decided to go with the hughes adapter kit for the mechanical fuel pump, carburetor and v belts. I pulled the motor that was in the car last weekend to get the last few brackets for the drive belt setup and throttle linkage, and found that the magnum heads have quite a bit more material and sit further forward. I was able to line up the power steering but the alternator is giving me trouble. First off the back of the alt case hits the heads preventing it from sitting straight and the three point adjustment bracket isn't able to sit as far back as it needs to. I could grind the heads and block where they mount and bent the adjustment bracket, but it would be an excessive amount. This setup however lines up perfectly. My only concern is that the short distance between the crank pulley would overwork the alternator bearing. Any thoughts would be appreciated. I also have an idler pulley with bearing I could make a bracket for to lengthen the belt.
