Yes, I used the cylinder/spigot base gaskets (.5mm). I don't know what the original thickness of the factory base gaskets were, but I suspect .25mm. This combination of base gasket without head gasket gave me a deck height of .035". I have never measured the thickness of the factory C2 head gaskets, but suspect they are something less than .25mm.
