10mm Head Stud Set, 12.7mm Longer Then Stock, Chromoly, Compatible with Dune Buggy

I have a normally-aspirated 2.3 litre race engine and ran these head studs for two seasons, just now split the case while removing these studs. No abuse or twisting for removal was required.These studs will not break but they will “bend”. Rolling them on a glass plate revealed distortion about the middle of the stud enough to need to discard two or three of them and get another set.Problem with stud bending to accomodate any misalignment of cylinder to case (block) is once removed in used condition, they cannot be reinstalled as alignment with through-holes for cylinder and head is no longer properly indexed.
