Thin smear of any kind of thick tacky grease around the cylinder bore.
Lay the twisted teflon around the bore, touch it into the grease, it will stick.
Touch the edge of the bore to push the twisted teflon rope into a smooth circle about 1mm from the bore.
Overlap on either side of any stud.
Slide the head on and torque on evenly.
Slip a length of solder into the plug hole and measure squish gap over the wristpin.

The teflon squishes very flat, less than 0.005" so variation is not a huge problem.
If any squishes into the cylinder (it has), it is not a problem.

'real' motorcycle mechanics don't have to deal with bolts & studs made of chinese steel that stretch horribly over time

Good point, even the best head gasket material can't help if still using studs made of chewing gum and not locktited in. The newbie threads make it pretty clear that replacing the hardware is one of the first things to do to ensure a good motoredbiking experience. Luckily they can be made or bought. Sick Bike Parts sell decent head studs for $10 and another $10 for the rest of the studs and bolts.

My grubee had excellent bolt quality. My front studs were actually 1/2in (or 12mm?) compared to the regular 10mm and were grade 5 studs I'm pretty sure

(I haven't fooled with my MB in over a month now so starting to forget things.... Trying to give accurate guestaments till I get time for my baby)

I imagine those dimensions are way off but the point that newer Grubee bolts are good quality and needn't be replaced is good info.

I know it's a 1/2 or 9/16 because it has the wide mount
They are very thick studs lol

Frank, studs and bolts and nuts are measured by the diameter of the thread, not the wrench that goes on the nut or bolt head.
So your head bolts do take a 9/16" or 14mm wrench on the nut, but the studs are only 8mm in diameter.
The front studs were 6mm on older engines, taking a 10mm wrench as you alluded to, and now are 8mm and take a 12, 13 or 1/2" wrench.

Confusing? You should try working on old British stuff...
