[Healeys] OFF WITH HER HEAD!!!

[Chris Masucci]

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
