Millions of vehicles are produced every year with heads that got built in mass quantities without having some specialty shop giving them a once over.
I’ve seen many new oem heads through the years, and the fit and finish of the heads being put on those millions of vehicles annually are on par with what many aftermarket suppliers produce.
It takes time to have each head scrutinized and corrected as deemed “necessary”....... and time is $$$.
