[Vwdiesel] 1.6l 11mm vs 12mm heads

What is this bushing, and where does it fit?  I'm pretty sure I have a 1.5
block I'll check again to be sure (1980 with 11mm bolts). It's the
remanufactured head I'm trying to figure out.  On a 1.5 if I look at the oil
return hole, will it be the same size as the oil sending hole?  On a 1.6 the
front (center?) oil return hole is larger than the oil sending hole?  The
return on the head has an extra chunk cut out of it that doesn't match to
the block (block hole is round), but it matches the 4-notch gasket.
