Thanks for your input. I will probably install new ones.

 

Unless they are stripping or rusting, IMO there is abosolutely no reason to change the nuts. If they are clean and spin off easy after loosening with a wrench, I'd re-use them.

 

Ok so I'm getting anxious! I can't help it! Any news? Are they still shipping mid May? Thanks!

 

any updates?

 

Good question people.

 

 

Patience.....

 

I'd disagree with part of that statement, if the locknuts spin off by hand after loosening them with a wrench something is wrong. A locknut should not spin off easily until the lock portion of the nut is beyond the stud, it should require to be turned back with a wrench/rachet or what ever tool your using. I only mention this because I have installed quite a few headers over the years and its a real pain to have header leaks and always be tightening the nuts. So if the nuts spin off easily you may be well served to replace them.

 

Well...I have R&R'd about 20 S2000 headers, and they are NOT locknuts. Remember this is an s2k forum, and that's the car I'm reffering to

Read again, I said nuts. Not locknuts.

 

The Honda Service Manual (2000-2003) page 9-3, says "self-locking nut", also says to use NEW gaskets & self-locking nuts.
