My buddy said to always use a torque wrench on injector hold-down bolts, I thought he was being too careful. Snapped one off in a 6.7 Powerstroke head last week.

Haha oh man, I gotta say I actually see it a little different than your buddy. I've been doing this for a while and honestly, I've snapped more bolts with a torque wrench than without one on these little injector hold-downs. The problem is those factory torque specs are sometimes way too tight for bolts that small, especially if there's any rust or dirt on the threads. Plus, a lot of torque wrenches aren't even that accurate in the low inch-pound range where those bolts live, so you end up cranking way harder than you think. I'd rather just use a short 1/4 inch ratchet and go by feel, like snug plus a little extra, and I've never had one break on me that way.

Your buddy was right. Those small bolts are easy to overdo. A torque wrench is cheap insurance.
