I know you're not asking me but i got (0) performance gain when i put my roller rockers on, some 15 years ago. but have lived well threw two 340s and now on a Hyd roller cammed 408.

EDIT SS not alu rockers

They do have a performance advantage when properly set up. How much, is going to depend on the engine combination.
