Are you 6 cyl folks using any RTV on the intake manifold areas of the manifold gasket? If so which RTV - Ultra Black, Grey, Copper?

If it matters, I'll be running the offy intake and langdon's cast 2-piece header.

Thanks, Tim

As a rule

never use RTV if you dont have to
only on the water port

Just make sure its all nice and clean
