Plug for SW headers EGR port

[orthodoct]

Just received new set of coated Stainless Works headers. I have a '92 S/N 0172 and it doesn't have EGR thankfully! How do I plug this port on passenger side header? Seems like the way to do it would be to tap and plug it. Hate to sound ignorant, but can you tap stainless steel with a conventional tap? What size bolt or plug? High temp antiseize on threads?

Thanks!

I found a short bolt that fits tight and just screwed/tapped it in with a small hammer. No antiseize on threads or anything else on threads. No threading of the EGR port required. I may have touched up the bolt threads for a tight fit in the EGR port using a grinding wheel.

I am sure I also have a set of SW Headers from Stainless Works with that EGR port removed by SW.

Thank you, my friend. Found something at Advanced Auto called "QuikSteel". Could use as adhesive around a stainless bolt. Supposedly good to 2400 degrees.

a 10mm 1.5 pitch bolt is a good choice. It was easy to tap by hand.
