The different lengths on the OEM valves tips (between intake and exhaust) is the same as what you are seeing with the aftermarket valves. If you still have have the 0.0625" clearance between the rocker rails and the valve spring retainer then you are fine.

This spec exists because as the tip of the rail rocker wears, the rails get closer and closer to the valve spring retainer and may deperss the retainer and release the valve locks from position. If your rockers are not worn and you have plenty of clearance (between rails and retainer), then you are fine. That being said, a roller rocker valve train with optimized valve train geometry is still the better way to go.
