16 ft/lb = 21 nm or 192 in/lb

Get a decent torque wrench, you'll need it and there is nothing like overtightening a bolt and stripping threads or breaking stuff that will make you wish you did. Some stuff like rocker adjuster covers is pretty easy -- they don't need to be tightened down that much, and if they weep you can tighten just a bit more or replace the o-ring, but for some stuff you're going to want to know you've done it right.

Hey guys another question. I will be getting the crush washers this Monday in the mail. Should I put those on with just the cap nuts or should I put a stainless washer on top of the crush washer?

There may be a locating dowel missing.  Typically valve cover bolts don't need to seal - they pass through sections of the cover that are surrounded by mating surfaces.  One might not be, but should perhaps pass through a locating dowel.

Parts diagram?  Always start with the manuals.
Not true, in all cases. My 750 DOHC has bolts with tapered rubber on them to seal off. If not torqued properly, oil comes out.

No need for a plain washer on top of the crush washer.  It's OK to use a smear of gasket goo on both sides of the crush washer just in case... 

If that doesn't work, try some stat-O-seals.  If they still leak at that point, I would be looking for a blockage in the head that's stopping oil flow into the camshaft.

hey guys I got great news put the cap nuts and crush washers on all the studs and they are no longer leaking!

bad news is that now there is a leak coming from the back of the head gasket :( im thinking maybe I should go back in the instructed order and tighten the bolts down again bc I tightened them all down to spec but it seems that some are more loose than others after riding for a bit idk if this is due to the cylinder head flexing or the copper washers maybe still settling in after heating up from the ride???

Also if I am not able to get it fixed by tightening it down again since it is a small leak is it still fine to ride as long as I keep an eye on the oil and clean the engine off so it doesn't get gunky?
