Oil drainback tube

A machine shop did that to me once. I delivered the head on my 69 slant with the rockers still on (didn't know, didn't tell me), then got a bare head w/ just valves back. I asked for the other parts and he looked around and found a cardboard box with most parts, but missing the special bolts and washers, then just shrugged. I had to go to a junkyard to get what they lost. I learned early not to pay big money to people who just pick their nose in front of you. Today, Angie's List and Yelp helps un-employ them, as they deserve. Worse is when a shop cops attitude for their screw-ups because you have "an old car", "six cylinder", "not a Chevy SB", or such.
