Pacesetter header with stock carb

I am attempting to install a header on my 1989 b2200 and I'm having a few problems.

1. What do I do with the o2 sensor? Can I just scrap it or will it cause problems?

2. Also, can the tubes that recirculate the exhaust back to the carb go too? If someone has pics with a pacesetter with the stock carb that would be helpful too.

Any and all help would be very appreciated. I'll be getting a weber soon, so this is just temporary.

my pacesetters came with an extension with a bunge for the o2 sensor, and the tubes i threw them away no issues with mine same year 2.2

Ok, I installed the header with few problems. Other than having to take a cutting disc to the bellhousing of the tranny and deal with some rusty bolts it went on fine.

I ditched the o2 sensor and the tubes and she runs beautifully.
