Default GM mls gaskets

Any one know what the thickness of the GM mls head gaskets are? Do they work well for FI? If not whats the best vendor to buy cometics from? Anyone ever reuse their cometics?

Lots of info available via search.

The GM MLS should be .054 and should be good for FI.

Cometics are availble from a few of the vendors.

Several have re-used their cometics - again search to get the available info.

Thanks guys!! I already have some .060" cometics and I think I am just going to reuse them. This will be the first time the heads have been off since I installed them. I sprayed them with copper the first time though...do you think if I hit them with copper again they will seal up?

I admit I haven't looked it up again, but when I did, the gaskets were like this:

GM composite (graphite): .054"
GM MLS: .060"
