Cap off metal line to heads? And another Smog question....

Sorry for bringing this old thread back to life, but does anyone know if it would be possible to simply cap the thermactor line from the head?
To be clear, I do not want to plug the heads. I want to keep the thermactor tubes attached, but cap them off at the end of the line (above the headers)

Yes. That’s how I did mine for the sake of doing it quickly. I left a short peice of air tube connected to the check valve and found a short peice of bar stock that fit perfectly inside and clamped it off.

Left it this way for years until I pulled the motor for HCI and finally removed it.

I could have removed it from the heads, but fortunately I didn’t because I ended up putting the cats back on and needed the pipe. By that point however one side clogged up so I always got a code for it.
