Valve cover - bolts are studs

Studs arrived and installed - I am a fan. So nice and I do like placing the gasket on the studs instead of inside the valve cover. It is a little troublesome on the drivers side (tight)

I might steal mygasser's acorn trick

A tip,
If using cork gaskets, wet the cork down with wheel bearing grease, very light, it will make the gaskets re-usable.
When I say light, put some grease between your fingers, and using rubber gloves, wet down the surface.
