Head Gasket ID

[sliderSR]

So I am wondering if there is a way to tell different types of head gaskets when all ready installed on the car OEM vs. after market. He said he had ARP head studs put on but I was not thinking about the head gasket then. So is there any tabs or little tricks to tell what head gasket there is? I just don’t want to tear down the motor just to switch out unless it is needed. Thanks for any help

Nothing? I guess I might have to buy one just in case.

The material. You might be able to see if its a felpro/factory vs Cometic/cosworth, but really, no not really a way to tell.
