[sicner]

Well Im sitting here at work and started to wonder what the thread pitch and all that is for rb25 head studs. Trying to figure this out now so that when I get off at 8am I can head out to get a tap and die set to clean the threads on the block for the headstuds. Thanks for the help guys
BTW YES I DID SEARCH S

Head BOLTS.

Use new OEM Nissan ones every time you remove the head, they stretch.

I believe it's M12x1.25, might be M10x1.25. I remember it's one of the standard taps I had in my collection.

Thanks for the input! I know to use new head BOLTS if I am using head bolts because they stretch, but I can understand this statement due to my lack of information. I have a set of ARP head studs to use sorry haha. Ill bring one of the studs to try and match it up once I get off work and try those first.
