I have had excellent luck with all summit products because they are usually name brand stuff with a differnt label on them and a hell of a better price.
If the machinist was shooting to get the tops of the studs equal to where they were stock, that could account for the lack of clearance. This is because the studs have a rather generous radius between the stud and hex for strength (arrow below, ARP stud). If they made the studs at a sharp 90 degree angle there, the studs would be MUCH more likely to crack/break at the juncture of the stud and hex. Dart studs have probably the least amount of radius.



If you're using 3/8" studs/rockers, this might be a good time to consider going to 7/16".

I don't know who grinds the cams for Summit, but they have a decent reputation.
