7M cylinder heads are made out of some of the softest aluminum alloy I've ever seen used in an automotive application.
Helicoil is the way to fix stripped exhaust manifold stud holes, but I've also had one of my helicoils pull out as well. Try using moly or antiseize on new exhaust manifold studs and nuts with a 20% reduction in torque. |
