Not true. Full deflection is almost immediate when normal aircraft hydraulics are powering the spoilers.
You're probably thinking of the airbrake, spoiler and lateral trim checklist step on the ground which only uses the ground test pumps and wing standby pumps to power the spoilers/airbrakes.
OP, the best source of B-52 flight characteristics is Chapter 6 of the Dash 1 (the Buff flight manual).
Also, a Google search on "Czar 52" will provide ample sources of the information and flight characteristics you're looking for.
