Yup GM or Felpro metal gasket for the lim.

Sc gasket... You don't need one just rtv that sucker and plug the 2 coolant holes (Billboost has a write up in the how to section)

TB gasket.. Felpros fine

A dab of black rtv on the corners of the lim. If your not using a gasket for the sc grey or copper rtv to deal that.

And decides coolant and oil your set
