arp makes a very good rod bolt lube. you need to understand that the rod bolt is tightened to yeild a stretch value. this places a clamping load on the bolt. if the bolts are properly installed [not binding at the shank]they should torque to specs.the use of lube greatly effects the actual load applied. a bolt can bind and yeild a false torque spec,then loosen up with use. i would never use lock tite....
