I have done it that way, but I didn't have enough unobstructed space to do it this time, so I bagged them all and labeld the bags like so: 7R-L, 7R-R, etc.

7R-L = 7 on right head (left side RFF in bag)
7R-R = 7 on right head (right side RFF in bag)
Then in one of those bags I have the 7R cam cap.

All these baggies are in an open handle office box, which can be moved around the garage with ease. This allowed me to clear up my work bench for the head portings & cc measuring.
