NB1 head to manifold stud thread size?

[wildbill]

I recently put a RB header, RB midpipe and GWR Roadster Sport II muffler on my car. During the removal of the stock California emissions exhaust manifold (man its a heavy SOB) one of the studs came out with the nut. I attempted to just reinstall it like it was a bolt as I did not have access to a new stud and nut at the time. Unfortunately I mucked up the first few threads. They're just kind roughed up. In conclusion I would like to clean up the threads for the installation of a new stud. What is the thread pitch of the manifold studs? Sorry if this has been asked before. My quick search of the forum and Google didn't turn up results.

I did the same thing on my 96 when I installed a JR header. But I used a second bolt on the first to help get the stud back in. Lucky for me it all went back on okay. I used some loctite on the threads so it would not back out again.

Unfortunately I don't remember the size or thread pitch it was so long ago. :fp:

You can find bolt re-threaders at Sears in the tool section for about $20.
