There is no problem with marrying up different rockers, fulcrums, pushrods and such. There are only a few parts of the engine that require that level of attention. Main caps, rod assemblies, and cam and lifter associations.
A rocker with perfect geometry will put the contact point of the rocker exactly on the center of the valve stem from closed to open. Doesn't happen that way in reality. What you're looking for is that at full open, the rocker contact is in the center of the valve stem. If you have that, the rocker will travel across the valve stem but will be nowhere near the edges. It should also be centered from side to side.
