A little help please!?

Hello all,
So I recently installed the Dyno Don headers . I was just wondering if . Where the header bolts into the y pipe is there a gasket that goes in there It wouldn't be a flat gasket . I would think it would be a tapered donut type gasket?? Does anyone on here know what I need ?

no gasket required, forgot what that kind of flange is called though. Ball and socket flange I think?

Ball and socket is correct, no gasket required.
