| -> Why copper?

|  The copper is ductile enough to deform under gasket load. 

If it deforms then how does it aid in gasket sealing?.

 Some people
| use stainless steel wire or MIG wire, which is very hard.  It's hard
| enough to dent the cylinder head on the other side of the gasket, for
| example, and the lump in the gasket can warp the head when you torque it
| down.

How much preload would do that?.  I never saw any serious warping from
using "safety" wire, with AL heads, course was 3" bore.

| -> Do, you go like with, .025" wire in a .025" groove .020" deep?.
| 
|  Pretty close.
| 
|  I dream of Wills rings, though.

Please explain, Wills rings
