I took off my intake runners last night and one came off easily. There was an o ring attached on the side that connects to the head and it sits down in a groove. The other one looked like the po sealed it with gasket maker or black silicone. Is there a place that sells these and are good quality?

Failing getting to a bearing supplier, you can try these online suppliers-I'd suggest Viton.

I want to thing the harbor freight metric oring kit had some that worked and it's only $8 or so. Plenty of spares left over.
