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.
I have a bin full of Look Similar and they were steel. ....................lm

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.
