On a 351W (stroked to 392 CID) Ford Racing Motor, which, if any, of the water pump bolts (standard rotation pump) require thread sealer? Of the eight fasteners that I removed (6 hex head and 2 allan head), there was no indication of any thread sealer previously used. Just wondering if that was a 'miss' or that none of these bolts threaded into water jackets, thus NOT requiring sealer.

Also, is it necessary to tighten the bolts on the back plate of these water pumps or do they already come tightly fastened? I've seen threads where the mechanic advises to LokTite and tighten the 4 backplate bolts.
