The Factory studs have only 7 or 8 coarse threads, and are torqued into the block to prevent water from leaking, so I was told. I worked for the Bullard machine tool co and we torqued all the studs into the castings that held covers and other components to the basic machine. Probably a good idea. Not sure if it's really necessary. I wonder if any other engine manufacture ever used studs? GM, Chrysler. engines never had them. Regardless, The flathead block deck surface is very thin is many placed and over torquing can warp the area and cause distortion of the deck. Unfortunately, there is no proof to any of this question one way or another, just something to kick around every 6 months or so. There s no right or wrong answer.
