We avoided disaster on our 5.2 Magnum build. ALWAYS inspect OOTB Heads !!!!

I wonder if there are the same QC issues with Fords and Chevy parts from these aftermarket suppliers?
Yes, just about everyone is experiencing the same. My speedmaster heads were perfect and were a true bolt on. Some had trouble with those as well. It comes down to some have a great experience and the very next guy has work to do. Assume the worst and inspect every part.
