Sure, but they don't NEED them for the engine to run with stock cams, if everything is timed correctly, as mentioned above. It's proper insurance against terrible work/murphy's law though.

Given that even with the reliefs it's an interference engine, it's 50/50 on whether or not the effort is required IMO. In the watercooled VW community, it's commonplace to slap a 16v head on an 8v block and not add reliefs.
