Been thinking of getting a head gasket. There are several types available, copper, steel clad, Fel Pro, and fiber with silicon squish. Started reading about how the thickness of the head gasket could effect compression but couldn't find any information on what the types being sold are spec'd at. Also is there a consensus of what a stock head should have?
All responses welcome, but be sure to associate to the type of head Aluminum, Cast, Low or High, or special.
Should be interesting....

With the current shortage of copper/asbestos head gaskets I measured the thickness of new and used gaskets.
The one new gasket I have on hand was 0.090” and several used gaskets 0.062” to 0.066”.
I have made a water bath and soaked a used one for a couple of days and then let it dry out. It had increased in thickness to 0.085” but I haven’t been forced to use it as yet.
