head stud height
 

Anyone know what height to set the head studs on a 2.0 S motor? Thanks

135mm.

Maybe slightly less if your cylinders and/or heads have been surfaced at all. The stud height is only an issue because of the internal hex "allen head" barrel nuts. If the stud were to be installed too high, the nut will interfere with the hex socket before getting the nut tight against the head. But if you use regular external hex head nuts, the stud height is mostly irrelevant.

Hope that helps.
