Stock LT1 heads can experience core shift so porting leaves them weak. Even heard of coolant coming through an intake runner. Much better off with aftermarket heads. Substantially stronger casting with better airflow, larger valves, etc. plus a thicker deck which is perfect for boost. I’ve had great luck with the Mast Black Label ones.
