nuts
 
All good suggestions, be sure to torque the rest of your head nuts down before fighting it, they get kind of "sprung" with only one being tight

nice if they were all like that.

The pictures OP posted were air cooled ... are there any air-cooled that the studs are not visible on cylinder or head when assembled? I'm not aware of any.

Lots of cylinders are cast with bores for the studs. I believe the 95mm and later are all "contained" studs

When Porsche increased the stud spacing from the 2.7 to the 3.0 is when the change was made?

All 3.0 from 76 on are contained and not visable.
