Cometic has been around a while with gaskets for bikes and some Foreign machinery. They started making HP gaskets for american V8 engines within the last 15 years or so. They have a pretty good reputation with the 5.0 crowd where, I believe, they initially ventured. I have used them in all types of engines, although not in any FEs. I have had no problems. Many of these were engines of aluminum or a combination of materials.
