Doug,
We use Cometics on most all our 14/5 and 15/1 combos.We generally spray them with copper coat and torque 7/16 studs and bolts at 75# and 1/2 studs and bolts at 85#.We also put a skim coat of ultral copper around and water passages if necessary,we use ultra copper on the water passages on all copper/o-ringed applications.These torque specs are with molylube.
