We avoided disaster on our 5.2 Magnum build. ALWAYS inspect OOTB Heads !!!!
Also, what's worth mentioning, is the comments being shared (and they'll keep coming in over the days) on this video on my channel show this isn't a freakish find, but a continuation of poor-quality control. If this video inspires even one person to take the time and inspect and find something like this saving their engine, it's worth it.
