Your answers, in order:

Are they Edelbrock heads? -Yes, RPM's
If so new or used? -I purchased them new, 6 years on them now.
Crane shafts have a right and a wrong way for install for proper oiling. Harlan Sharp can go on either way. -Definitely on on the correct orientation
Like asked above were the shafts banana grooved? -No
If so were they done right. Some guys make the grooves to long and the oil sneaks out past the rocker. -Again, not grooved
Did you limit the oil going to the head. Some guys do. -No
Were the rockers shimmed right side to side? - springs between them with steel rings for wear protection
Were the rockers checked for proper sweep on the valve tip. -perfectly across the center
How many runs did the rockers have on them? -a few hundred and 1500 miles of standard driving and road racing

I personally never use those springs as they do not limit rocker placement properly. I usually take 3-4 hours setting up rockers the right way.
