Installing a aftermarket air filter assy is a bad idea. It will not filter near as well as the Donaldson OEM unit the truck came with. There is no HP gain whatsoever.
The head studs are necessary when you tune the engine at a certain point. Some tunes are safe with the stock head bolts. SCT with the SRL is a tune that can be used w/o studs.
