Phil, IMO there is absolutely no tech reason that any specific torque need
be applied to these cyl. heads. They screw into a flat metal to metal
interface and can move no farther, this position leaves the correct squeeze
on the O-ring. A screw driver can easily achieve this metal to metal
contact and no further torque is needed. Thus, a drag link socket is not
needed for installation nor for removal, as they can easily be removed with
a chisel if not with a screw driver.
