P4529117 is a newer number for P4532060. Same manifold, different part number. I found a pic of the P4532061 and it looks identical to the other 2. These are nothing more than aluminum versions of the factory cast iron HP manifolds.
I used to have the RB version on a 440 years ago. It's exactly the same as the cast iron piece...weight savings is the only advantage.

This is what I have found out about this intake on-P4529117, the rpm range is from idle to 5800 and fits stage IV,V and production heads. What is your source for this? If it is an intake that is fashioned after the factory intake for a 440, I agree with Lew. Power will drop like a stone at 5200. The intake is the cork on a factory 440. If you insist on that intake and want to up the power and rpm range, mill the divider, add an open space as room allows, and cam up slightly from stock.
