My BBC GM Performance Parts Aluminum heads came from the factory with Helicoils in them. <img src="/forums/images/graemlins/confused.gif" alt="" />


while this picture isnt 100% accurate.....it is a good picture of the insert (the lower 1) we use at the dealer.

the picture isnt 100% accurate though. hes not holding the actual helicoil spark plug insert. just a standard helicoil.

having seen them side by side and used them i would never use the helicoil brand insert again. we actually had a truck come in about a month ago with the helicoil insert blown out.

this is the actual helicoil insert.....
