    I had really bad issues with these, not sure if others have as well. They are about 1/4" shorter than the stretch bolts, and they stripped out when I torqued them to the spec of 15ft-lbs. Vendor suggested my torque wrench may be out of calibration, and it may, but the bolts only grab about 4 threads before they start grabbing, I don’t think that is enough on the aluminum heads, I think they are just too short.

    I ended up putting helicoils in is so horrible deal but thought I would ask of others experience.
