The rotating assembly on this engine (from mazda) had a B and an E. The E is heavier than the B. What gives? And yep they are spotless. The E is 1.5 side seals heavier than the B.

Close enough.
The rotors never have the same amount of oil in them anyway, so they pass each other in balance as you brake and accelerate. The rotors balance each other (just about) and the counter weights just take out the rocking couple. The wiggle in the shaft caused by the rotors not being exactly opposed on the shaft.
Use the rotor. No problem.

believe it or not, having different letter rotor doesn't make enough difference to do any damages to the engine. Mazda specifies 50 grams in tolerance so if you take everything into consideration, pretty much anything and everything is interchangable and still within spec.

ok i finally got off my *** and looked up the letter thing.
its in the r100 shop manual, and the 74-75 rx4 manual, but by 77 its gone. in the 77 and 83 books they dont even give any kind of balance wieght.
