Factor cast iron manifolds
Is there a certain brand / type of gasket to seal these to the engine?
Any other sealant needed?
Thank you!

They aren't "factory" but I think exhaust gaskets by Remflex are the best there is.

100%. Remflex is the ONLY exhaust gasket to use. Headers, Factory logs and Factory RA/HO manifolds
