Help! Can't Fit Factory AC with tall valve covers...

[elks]

I am at the very end of building a 350 for my 72 truck. We are having a fitment issue with the belts. At first this was with both the AC and Altenator. We found a belt slightly longer for the alt and when the altenator is completely maxed out the belt barely works.

However we can not come up with a solution at all for the AC. Here are the pics I have. The ac compressor when rotated all the way in hits the valve cover long before I can get the stock belt to go on. If we went up belt size, I do not believe there is enough play left to pull the belt tight. What is the fix? I have roller rockers, thus the need for the raised valve covers.

Also to get to this point we have to redesign the lower bracket to get it spaced out and to "fit around the header....









Let me know what you think... Is there an aftermarket solution for the brackets with out going to a completely different system?
