So, I bought these new headers on the internet. they have these threaded holes in them (pictured above) which my original did not have.

My original had a hole in it, that's why I needed a new one :) but not threaded....

Any ideas?

some headers had connections for a gas analyzer.
The thread should be a R1/8 (conical).

The old plugs were #000047113 (now 78010091A). Not sure if #78010071A is the same.

got the washers, too? Applying some anti-seize is recommended.

I was wondering about washers. are they special? or would the right size washer do?

that should be ok, too. It should just be a washer that also can seal.

you want that bolt to sit airtight so you use a washer made out of a softer material than steel
