HelpMe

Any advise would be greatly appreciated, I rebuilt my Olds 455 and decided to go with the Edelbrock Heads, my Altenator Bracket now does not fit, the Air Conditioning Compressor is having the same issue. I haven't got to the power steering yet but because it's mounted on the lower section of the block I think it may be in the clear. And advice or past experiences would be greatly appreciated,
Thank you
Your fellow BOP friend...
