been using that gasket for years..... for two reasons. It's what the auto parts stores give you over the counter, and they are cheap. I've NEVER had an issue with them.
Me too, I was afraid 11:1 would be pushing it , but they have been good!
A couple of years ago at the Indy swap meet a guy was selling them for $5 apiece. I bought a couple sets, but should have bought all he had. He had a big stack of them.
