Hey bud!  Originally, I used a Shimano Hollowtech with Gil's shims to finish off the build and test gearing etc but have since swapped it over to a Bullseye.  The cups pictured do look a little like modern Bullseye,but are actually some black cups that I had available.  The Hollowtech worked great with the cranks though.  Good eye!
I hope all is well on your end Nick.
