    What is the size of the star stud on intake manifold and egr valve stud. I am trying to take head off to change head gasket, but don’t have the socket to fit that star(reverse torx?).

    This is from memory (beware) but I'm gonna say E8 Torx.

    Yes, E8 is correct for the EGR attaching studs. I just now checked.
