How thick is the oem headgasekt?

[thmehr]

HI
I am replacing my head gasket again. How thick is the oem head gasket from the factory? I what to have Cometic build a gasket that matches the correct thickness to keep my timing correct.

Also, has any tried using Hylomar Universal Blue as a head gasket dressing? I have read some good things about this product, but I can not find much info on Hylomar when used on a supra.
Thanks

There's been a couple guys used the Hylomar on a stock composite gasket with success...same for Permatex copper spray and Brake Quiet. I would NOT USE any type of sealer or dressing on a new MHG...they come from the factory with a Viton coating that is plenty good enough for the initial seal. The above products contain chemicals that attack Viton. Read this:
