Indy 440-25 intake

I picked up a 440 with one of these Indy 440-25 2 four cross ram intakes on it. What is the RPM range on this intake??? Is it streetable at all?? It has a pair of nearly new Edelbrock 1405's on it. The top half has 3 of the bolt hole tabs broken off. The machinist said $40 each to fix. Does that sound about right, and would it be OK just putting a washer on?? I know I didn't just ask that did I ?? Also what's the set up worth?? I guess that's enough questions isn't it?? LOL. Any help would be appreciated. Thanks, Woody.
