The valves will get a cut taken off the stem where the rocker touches it so whatever match that existed there is gone. Notice the rocker fulcrums, it looks like they have roller bearings and they're remaining with the individual rocker arm. The engine probably has roller lifters which are remaining in place. Someone mentioned spring pressures, the heads are getting a valve job.
Only place where things won't 'match' are the pushrod ends and they spin when the engine runs, there's not going to be a really critical wear pattern there. That engine, when reassembled, will run for many thousands of miles more assuming the only thing it needed was a valve job.
Agreed. In fact, when I re-built the 3.1 for my wife's Grand Am, I sure didn't keep track of the order. Even the (roller) lifters were indiscriminately pulled and disassembled to clean the coolant laced oil out. 30,000 miles later, it hasn't missed a beat.
