Hi Dave. I generally don,t bother with paper gaskets I just use silcone sealer used sparingly. I use paper on the rocker covers because of having to remove them for tappet adjustment.
 Re the bolt torque, I have been messing around with nuts and bolts ( not just on bikes) for over 40 years and I would suggest (although there will be those who disagree with me), that I can tighten a bolt to fairly near its correct torque just by feel. If you cannot do this I would suggest fitting some bolts into holes in scrap metal and tighten them by hand and then compare this by checking with a torgue wrench. I think you will begin to get a "feel" for it also not just relying on the torgue wrench.  The main thing to remember is that tapped holes in alloy will easily strip if overtightened. All the Best and happy new year.

Hi Dave I agree With Goldy silicone sealer is great, use it on my S7 rocker box which only has 3 studs tends to warp very easily. I drilled the nuts to fit locking wire no need to tighten them very much,I just use copper wire stripped from electrical cable , has worked fine for many years.Cheers.

I prefer to use Permatex Ultra or Hylomar (its predecessor); it's easier to remove and clean up than silicone RTV is.
