Ok, I made some block off plates where the air tubes connect to the header or manifold if stock. Do I need to block off the flange where the air tubes bolt up near the firewall. Its a 3 bolt flange

 

I know some people answered my other questions about the air tubes. Did you cut your tubes off somewhere else? I machined my own plates for the header side of the tubes, Just need to know what to do with where the tubes attach now

 

what do they attach to? If its the pair valve you can just remove that whole system.
