I just installed a ceramic coated Downey header this past weekend. I have 2 questions for other people who use Downey headers:

1. What is the best thing to use to plug up or block off the hole in the center of the header flange made for an O2 sensor? Right now I have a brass plug in it, but it is not permanent.

2. The heater hose is very close to the header. Its the one that connects to the back of the head. I think its #2, or #1, I dunno. Anyways, its awful close :pat: and I don't think it will last long with the heat. What do you think?

Thanks
