[Healeys] OFF WITH HER HEAD!!!

[Dave Russell]

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
