I'm freshening up my 572 Hemi,it has 7.100 Molnar rods withARP 2000 bolts that have probably been torqued 5 times between checking bearing clearances and assembly using the torque plus angle method with a Snap-On torque wrench. I never measured the bolts when they were new but this time I bought a point micrometer to measure them and they are all over the place, with up to 0.006difference from shortest to longest free length.Are some bolts stretched or do the free lengths vary that much.Has anyone measured theirs when new?
