Head gasket

Hi guys I'm having trouble finding what head gasket is fitted to my car. I know there is a tab on the gaskets that is supposed to have holes in to indicate what gasket is fitted. I have found a tab on the gasket on the injector side towards the 3rd injector and there is no marks or holes on it. Any ideas am I looking in the wrong place

You're looking in the right place.

You're likely to have the largest thickness I guess.

as above thickest version

You get 1,2,3,4 and no hole gaskets.
