I thought it was critical to assemble/torque to the same values that the parts were machined/torqued to including what lube was used. At Pettis if it was machined/torqued w/ARP lube at x amount of torque, then that's where it needs to be..........I know Jason said the ARP lube had changed over the years and found a few issues w/it but now landed on the stuff they like best...............
