B Block Conversion and Power Brakes

Planning a major drive train conversion on my 318 '72 Duster after the New Year.

I have settled on the 383 for the conversion, but also have a 440 as well. Currently both are cores that need rebuilt, and I have 440 Source Heads that have already been checked out. Looking at using Schumacher Headers, since I have power steering. Last the heater issue is already dealt with as it was an A/C conversion and the blower motor is inside the cabin.

The issue I'm concerned about is the brake booster. It currently almost hits the 318 valve covers, in fact I couldn't fix a valve cover gasket leak very easily recently.

Do I have to eliminate this and go back to manual? Is Hydroboost an option?

If I went with Hydroboost option, could I upgrade to the 440?
