helicoil in heads

You are correct on the tang. I just read the package and never noticed that before. I have been doing them wrong myself. How do you get the tang out of the hole?? Skinny magnet on a stick?

However, there are cases where there is more thread than the standard helicoil is made. The design standard for thread engagement is 1 1/2 x diameter of thread. Look at the head and rocker arm bolts.
