"7/16 Exhaust Stud Kit for 7M. Another thorn in the 7m's side is the exhaust studs. Most of you know that this is a big problem when you go to replace a manifold and the studs strip before you get even close to 29ft/lbs. Some people have them start to back out on their own creating a big exhaust leak. I have seen engines where a stud is just completely missing So I came up with a fix/upgrade. I go up to a 7/16 stud with coarse thread on the head side and fine on the manifold side with a 7/16 helicoil in the head. The coarse side has larger diameter threads that will not strip out of the head. The fine side lets you get accurate torque like stock. I use metal locknuts like stock too. I have had helicoils of the origional stud size pull out because the aluminum gets brittle and weak after all those years of heat cycles.Kit includes:Eight helicoils (one extra just in case), seven studs, seven metal lock nuts, one 29/64 drill bit (standard length), one tap holder tool, one tube of cutting fluid, one tube of antiseize."
