Parts swap on industrial 318

We are trying to get 1959 Plymouth Fury mobile for the first time in 40 years. We picked up a low mileage 1972 318 from an RV. We disassembled it for inspection, pistons were clean, can still see cross hatching in the cylinders and all the bearings looked good. I understand these industrial motors are a tad different from the car motors. I noticed it has flat top pistons, a goofy cast iron timing cover, the heads are a little different and it has a double roller timing set. The motor did sit for awhile and the cam developed some rust. Figured we may as well do a cam and intake on this thing while it’s apart. Will regular 318 parts work? I’d rather not put a 2bbl intake back on this thing. We have some headers as well but aren’t sure if they will fit in this car or motor at the moment.
