You'll need to answer that one yourself by verifying proper geometry when installing your new rocker arms.
Basically, you want the roller tip to roll from the intake side of the valve tip, across the center of the tip (at approx. mid-lift), to the exhaust side of the valve tip (at full-lift) and back. If the pushrods you have don't provide that, you'll need new ones.
Don't mean to sound like a CompCams rep here (just quite familiar with their stuff), but the Hi-Tech Checking Pushrods they sell are the coolest tool for measuring required pushrod lengths I've ever seen.
Hope you're existing pieces work out for you...
