Get a metal scribe with a "pick" end, or even a bent spoke with a sharpened end, and probe around in there mate, you should be able to feel the "bump" between the gasket and port.
Unless it sounded like me farting after a huge christmas lunch and more booze than the average man can drink and not die from, there are gaskets in place. They get covered in carbon and they're hard to see, but they're there. Cheers, Terry.
