Stock exhaust Jet-hot coating

If they don't leak that's good. The ones I've seen get compressed and tend to cling to the head so it might look like you're seeing only the outside of the exhaust port. If leaking or if you ever take them off again, one way to get the gaskets out is to tap one side if the old gasket using the blade if a screwdriver like a punch then tap the opposite side until the gasket gets a bend in it and partially lifts up from the surface enough to get a pick behind it and pull it out.

Thks. Deanohh that is probably what happened. What is best way to check for even a slight leak?
