If you have dents to repair in both headers, another method is to remove them and then bolt them together using a piece of plywood with the vinyl sheets on either side to isolate the headers from each other. It simply saves the effort of moving the primary side block off plate from one header to the other. However, bolting the two headers together took a bit longer than using the single plywood plate, as the bolts on two of the header flanges were very difficult to install nuts on. Ultimately we had to use 2-inch bolts and two 2-inch sections of 3/8-inch threaded rod (all-thread) and grind down a thin nut before both headers could be joined.
