Log manifold downpipe gasket?

Is there a gasket that goes between the manifold flange and the downpipe like a donut gasket or does it just bolt together like a ford ball n socket flange

On the GTO's, it's a tapered seat fit, with no gasket. The male taper on the manifold engages the female taper on the head pipe. Needs to be square to seal.
