Dave,
Viton, Nitrile, whatever you want. MLS head gaskets are NOT meant to be
reused, and none are designed to be.
Your dice($), your roll.
Cheers,
Chris

Hi Chris,
Note in the reference that I cited it says:
--- "A thin coating (0.001- to 0.0015-inch) of nitrile rubber or Viton is
used on the external surfaces as well as between the layers to provide
maximum sealing." ---
There are several versions of MLS gaskets. In this case, I believe the DWR
gasket uses Viton, not nitrile, & is reusable as Michael said.
I agree with the torquing procedure for ARP studs, except Viton coated MLS
gaskets don't have the nitrile sticking problem.
Regards,
Dave
