Swapping from manifolds to headers help please

[drsbub]

I have recently started working on my 85 Sierra C1500 and decided to go with headers instead of using the manifolds.

My question is what all can I remove now that I am not using the manifolds?

The manifolds had smog lines running into the front of them and I am not planning on reusing any of the smog crap that is there. I am not looking to gain anything but less clutter in engine bay.

I have a 350 tbi motor. If that matters on opinions.

I don't know if it matters or not but I will be running open headers not going on any long trips in this thing.

I have searched threads but no one really explains anything about the removal of this smog stuff.

Any advice would be appreciated. Thanks.
