Horsepower with mileage options

I think that the way to go would be keep the iron heads, stock 340 cam, 4bbl intake either stock steel or aluminum, and carb to match, dual exhaust and a set if 355's out back. Put all the stock parts on the shelf to put back stock if ever wanted. What do you guys think?

I think this will be a good plan...

The aluminum heads and 2 bbl intake are not worth the expense vs power gained for your application...
