New Edy heads, poor quality control what to do

I just have to ask ( and I'm not tryin to stir the pot) I understand that head selection especially aluminum for a small block mopar is hard, but how does edelbrock justify those high prices and then such sloppy work for their cylinder heads???? For the price I've seen and read about I would think that the heads shouldn't have that many problems, and then would need 1500 + , more to "correct" the problems that should have not been there....Again I'm not tryin to kick up any problems, just was wondering.....
