After doing some research i was sort of confused...i think both these lines run to the cat one being the airpump line and the other the secondary injector something or other acv? Do i just put a block of plate on? or remove them entirely? Thanks for the help once again!

Thats correct, one is for the cat the other is to the LIM

So what do i do with them? remove them where they connect..i can see the airpump one pushing air from the airpump but what does the other line do? suck air into the uim? What thinkness of material can I buy for a block off? Would aluminum work? i was going to fab an intake heat shield can i use the same materials?

I removed mine, and blocked it off. What I did was cut it at the point where it turns into a pipe and block it with JB weld. The temperature will never get hot enough to do anything and 10 psi is nothing JB weld.

Take them of from the LIM and put block-off plates on, I made the B-plates myself from aluminun (if I remember correct the plate was 10 or 12 gauge) and high heat RTV silicone to seal, that's it.

I took off all the pipes and blocked mine off at the cat using 1/8" Al and the same pattern as the pipe flange.

Eventually, you should block-off your ACV. But since there are check valves where those pipes are routed, you do not need to worry about exhaust gas getting into your engine bay.
