As mentioned before there is nothing wrong with the Cometic. If both mating surfaces are prepped correctly (ie decked) then you will be ok. If you blow one at that point chances are you where going to blow whatever headgasket was in there. It's always easy to blame somebody else. With that said the Cosworth unit is very good as well. The Cosworth headgasket is 90.5mm bore already, and Cometic can make it any thickness you want.
