Are they MSD 50s?

[GN84Turbo]

I just picked up a set of MSD 50s, but i have no way to identify them, except for the serial number on the top of each injector.

6280 17104487

This is the #, can anyone confirm these are MSD 50#ers?

Try the link below. Input the model number off the barrel and search.
The numbers are for a Rochester #50 injector.
