Purpose of small bracket above #2 spark plug? 1970 LS5 with AC

What's the purpose of this small bracket above #2 spark plug and in front of the exhaust manifold?

1970 LS5 with AC (compressor removed in this photo).

I don't see any picture.

Trying again. I see the photo but no paper clip.

That looks like an oil pressure gauge line bracket.
It is supposed to be bolted to the cylinder head at cylinder #7.

Thanks Rick. That bracket is missing on the left head.

I wonder if the cylinder heads were swapped left/right during overhaul...

Yes, that looks like an oil line bracket (bent over). And yes, I would say that was mislocated because of the head swap left/right at some point in the car's past. The plastic oil line from the gauge enters the brass fitting with the compression fitting just above that, then there is a junction between that and the steel oil line and its fitting coming in from the block. The center of that junction slide into that notch in the bracket.
