Well, I'd never use it. I'd use the very thin gasket material, it's usually available at auto parts stores.
This is the stuff I have, and I got it on Amazon as I recall: Fel-Pro 3045 Gasket Material. However, I see Advance Auto Parts Has it as well, and I could pick it up locally: https://shop.advanceautoparts....rial-3045/19780351-P
