304 block head surface

Hi there I'm reinstalling my head and there are two metal sleeves on each side of the block on drivers side and only one in front on passenger side. These sleeve are raised and help to hold the gasket in place and since I'm missing the one in the rear on the passenger side I'm worried about the gasket slipping when I drop the head down. Any suggestions? I'm not using gasket sealer so I guess my main question is is that sleeve absolutely necessary or could I do this without that piece in place? If I were to replace it where would I fin an exact replacement? Is it something I'm gonna hafta fabricate? I so where do I get the material? A piece of 1/2 inch copper fits perfectly over the sleeves so that is the rough outside diameter.

Was it always missing or maybe did it stick in the head when you pulled it off like mine not sure where to find a replacement but sure someone on here will chime in and have one on a old block.
They say money can't buy happiness but it can buy Jeep parts...and Jeep parts make me really Happy.
