Technician A is correct because it's important to keep valve springs with their respective valves during disassembly to ensure they are reassembled correctly, and testing for squareness and proper spring force is crucial for engine performance. Technician B is incorrect because, typically, the exhaust valve is smaller than the intake valve, but not as much as 50% smaller; the size difference is not that extreme.
