Antifreeze leak on header flange

Yeah I was going to say that this is not the best place for RTV, there are better products out there and I think all small blocks have the same problem.

So should I use some sort of sealant like Indianhead, or #2 Permatex that others mentioned? or go with Teflon tape as Vitamin suggested? The nice thing about Teflon tape is I could just remove the bolt, dry it off, wrap it in Teflon tape and put it back in.
