I want to buy a RB Header for a 12A 79.. "Engine-to-pipe and heat exchanger gaskets are not included, but are available separately or as part of a complete exhaust system." This is from the RB Site so if I install the header do I need both gaskets? engine-to-pipe and heat exchanger gaskets? I don't really need the heat exchanger gasket since installing a header won't do anything for the heat exchanger gasket right?

Thanks for your help...

 

You need both gaskets...the header bolts to the heat exchanger...I ordered mine from Mazdatrix and told them to include the gaskets I'd need...
