The nut is the same thread as stock, with a smaller 11mm hex.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eWhy brass instead of the stock nuts?\u003c\/b\u003e Brass does not rust onto a steel stud, so the nut comes off next time instead of snapping the stud out of the head. The smaller 11mm hex also clears the tubes on large-diameter headers where a 13mm stock nut and socket will not fit.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eWhat wrench size do I need?\u003c\/b\u003e An 11mm socket or wrench. A thin-wall or 1\/4-inch-drive 11mm socket works best in tight header flanges.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eCan I use them on the intake manifold too?\u003c\/b\u003e Yes. EMPI sells them as intake\/exhaust nuts. They are commonly used to hold dual-carb intake manifolds down where clearance is tight.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eHow many do I need?\u003c\/b\u003e A Type 1 engine has 8 exhaust-port studs (2 per port), so one set does a complete exhaust. Intake manifolds need their own set.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eWhat is the part number?\u003c\/b\u003e EMPI 43-6051-0 (often listed as EMPI 43-6051). The bag of 100 is 43-6051-B.
