Will the ar103 plugs fit in my 327 if they fit in my lt1 350?!---

I cant get ANYONE to answer this. I use ar103 plugs for my nitroused lt1, and want to use them in my blown 327 too....but am not sure if the threads are the same?! PLEASE HELP, thanks!!!---

99.9% of 'American' motors use 14mm threaded plugs....even Fords. So yes, the threads will work just fine.

The only thing you'll want to verify is the reach on the two different cylinder heads.
