Moly rings do NOT take longer to seat in a properly prepared cylinder.
Was the block torque-plate bored and honed? What grit stones were used? Were the bores plateau-honed? Were the rings installed correctly (second compression rings installed upside-down will cause what you describe)?
What is the brand and part # of the rings used? Perhaps they are low-tension rings.
