im looking in ording a Cometic head gasket and they told me that i need thickness and bore size of the HG. I know that the Bore of a b16 is 81mm but that is not the same size as the HG is it? i believe the stock HG is 0.026in thick but i am un sure.
Thanks for all the help

I believe stock is .029in. The Cometics are .030

 

so what about the bore of the HG???? is it going to be 81mm or bigger than the bore size of the engine
