lol at Keegan.

Yes they do. They all did. They're for the thermal reactor. And yes I suppose you could JB weld them and hope that it'll hold up, but it's easier to just get a header and not worry about it. The header flange will cover those up and you'll forget they're there. Make sure to get the correct exhaust gasket for the year of the engine if it doesn't come with the header.

I just recently had extractors put on my 12A. The headers basically blocked these off with the gasket.
