The helicoil repair went very well. The kit came with a dozen coils, the insertion tool and the tap. Very straightforward. I may just do the other exhaust manifold as well as it has been removed a number of times and the softer aluminum is not holding up at all well to the rusty steel studs. The ARP studs are a beautiful hard stainless finish compared to the stock studs. The 3/8" jetnut is also MUCH easier to attach a socket to in that tight space.
