Cylinder head washers

Is it necessary to use crush washers on all 8 studs?
Can I use 6 good steel washers, and put crush washers on the 2 outside front studs where the oil pressure is?

Put them on the rotor and see if they stick.

They do stick. But they are the correct part number according to the fiche for my engine number (CP77E-1001821).
It specifies 90441-286-000 x 8.
