Inliners International Forums General Discussion Hi Performance New Guy Here. 68 Camaro with an L6 250.

Oddball question: do you guys recommend silicone for the header to head seal or a gasket or both?

I was watching TV and a show mentioned using silicone for the header. That made me do some online digging. I'm seeing more opinions than posts on the subject.

So... using Langdon headers on a 250: metal gasket, silicone, or both?
