There’s 2 kinds, cork and paper. I’ve not used the paper type yet, but some really experienced guys say that it’s far better. The paper gasket is much thicker than the cork gasket. You can find it at RMEuropean.
If you are putting on an I-J scraper, IMO the common solution is to put some gasket goobage between scraper and block, then a gasket between pan and scraper.
