Found a decompression shim whilst rebuilding head.

Morning All -
Engine advice needed please!
Currently have the head off of my M15a suzuki ignis engine. strangely it had a decompression shim - solid aluminium, c 4mm between the old head and head gasket.
The only reason I can think of is that the old owner was going to put a turbo on it, could I just install the new head gasket without the shim or is it needed?
If so would I need a head gasket either side of it?
