This is something I am very familar with. My Ford FE motors typicaly need the rockers shimmed.

What set up do you have?

NMRA Pure Street is a class where the rules state that participants must use a hydraulic lifter (Non-modified). Somehow they are able to rev those bullets to 8,000+ without lifter/valve float.;)

thats tricky stuff, i have heard tighter springs in the lifters or oil restrictors in the pushrods some how??? i think there is a certain lifter people use to make that happen, what kinda rpms you lookin for, and do you have the rest of the motor to support the rpms??
