Important Installation Information

Before using our HCR N54 Head Stud Kit, your engine block and head must be machined to accommodate the larger studs, replacing the fragile M9 bolts in all four corners. The original head bolt passages need to be drilled out to fit the 11mm studs. We offer comprehensive machining services to ensure a perfect fit.
