Playing Devil's Advocate, what does it matter if the torque is 60lbs, -70lbs, -80lbs ...or anything in-between??


I have a cap grinder, and I have found most core caps are really not flat in the flange area and so 'a thou or two' off the cap helps the cap mate parallel with the shims and main saddle of the block. From there is really is more about keeping the cap from "walking". Theoretically if the cap mounting surfaces are in a different plane by a little and the engine builder torqued the bolts at 60lb when it was line-bored -and the owner torques them at 80lbs this time, I suspect you will see some deflection & distortion on the cap. In Ken's situation this may not be possible but we always try to use a torque wrench to loosen the bolts as a way to know what to re-torque to.
