Sealant/RTV on Intake Manifold Gasket?
 

I'm installing a lower intake manifold on a 22RE. I have an OEM gasket for between the lower manifold and head (part no. 17177-35022) and I'm wondering if I should use any kind of sealant or adhesive here. The shop manual just says to install it but I've noticed the later gaskets from Toyota for the 22RE have a rubber bead around the ports but this one is only fiber and seems a bit thin to me. I feel like that bead must have been added for a good reason.

I used Gaskacinch on that gasket. I didn't use anything on the gasket that goes between the lower intake and the plenum. I've pulled the plenum a few times, and was able to reinstall using the old gasket.
