I'm not sure if the rear fender of a '71 1302 differs that greatly from a '74 1303 but here is what I experienced.
I had 16x6.5 wheels on mine. I also had TopLine rear disk brakes, so I don't know how much that altered the equation. To get the wheels (tires, actually) near the inner lip of the fender, I used 8mm (aprrox. 0.315") spacers. The offset of my wheels were 42mm (approx. 1.654"). There is some room to operate. I'm not sure how much offset I could afford such that the mounting surface would have moved the inner edge of the rim more to the inside. I had no issues with the rear fenders so I never had to experiment. 8.5-inch wide wheels may be tricky under stock fenders. I wish I could answer your question more definitely. Maybe someone else can. If you can measure how far "inside" you can go, maybe you can calculate what would work.

I don't think the 8.5's will fit stock fenders. I have 8et70s on my 1302 rear with 986S brakes and it 'just' fits. I had to trim the body mount in the fender a touch so that the tire (225/45) doesn't rub on compression. With 8.5 the offset is typically 52 or 55mm, so you'll be out too far with Porsche brakes. With stock drums or the regular rear disk kits (most are +8mm per side over stock drums) I think you'll be just on the edge of the fender with a conservative tire choice.
