The car is a 1978 Cobra, 302/auto. Do the smog tubes that attach to the back of the heads require a gasket at each attachment?

Anyone? I’d appreciate the help. I’ve researched all over the place but have not found any information on it.

I think most of our Mustangs haven't seen their smog tubes since the 80's. And since no one sells such gaskets, it may not be a very practical question. I have no idea how the originals looked, but if they're flat machined surfaces a dab of copper RTV never hurt anyone. That's how my '95 was before deletion, no gaskets or sealer from the factory. But that's two decades later.

Thank you for the response. I made my own this morning and attached them. Should work.
