So I am putting the last few pieces on my engine before it goes back in and I have the plastic pieces that go under the manifolds. Just curious what the preffered is to do with them. do they go on bare? Do you use gaskets? Do you use Toyota black? What should I use?

Gasket goes on each side of the insulator. I don't use any sealer (my manifolds are flat).

I thought that was what went on there but I didn't have any in my rebuild set Well, time to order them up Thanks Gint
