New Edy heads, poor quality control what to do

I got my edelbrock rpm heads about 5-6 years ago and they were terrible. I had the shop that did my motor do a quick valve job and some minor port work. The guides were so tight that several valves would hardly move by hand with the springs off. The worst part that even my shop missed that I found was the oil hole to the rocker shafts-one head the hole was only broke 1/3 of the way through and the other head was not drilled through at all- I had to drill the last .030" of it! I have no doubt if the shop wouldn't have redone the valve guides or if I hadn't checked the oil holes these heads would have wrecked my engine on break in.
