Recently bought a motor and realized that the exhaust manifold had a leak. so i went to tighten the bolts for the header, but they're stripped. so i've decided to hellicoil. but my question is this:

I was wondering what the thread pitch was for the exhaust manifold were on a b18? i believe they're m8x1.25 but I'm not positive.

thanks for the reply in advance.

 

yes 8x1.25
