ARP XU M11 head studs

[Dave]

As Ruan said for head stud threads, and yeh they will fit find, just theres not enough threads on the top end of the studs so you need to make a small spacer, could maybe get away with ordering like 4 sets of ARP washers and stacking them, but bit of a bodge...I just got someone to turn up some spacers on the lathe...had no issues at all at 60psi

If they were cut they must have been soft material? Normally studs are hardened/have to be ground.
