I'm building a bike from the ground up and I installed Ultegra HollowTech II BB cups and an Ultegra 6600 crankset. I tried spinning the cranks afterwards and after 2-4 rotations the cranks would stop. On another bike with a cartridge BB square taper, I spun the cranks and they spun many many revolutions until the cranks stopped.
Is this right or did I botch the ultegra BB/crankset install ?

by my experience that is normal. i installed an xt external bearing bb in a bike just recently and the owner said the same thing you are. that resistance goes away with time and the grease works in and the seals wear down a bit
