The correct cylinder head gasket

Hi, could you help me with selecting the right cylinder head gasket. I've been on VW heritage to buy the bits and pieces i'll need to replace it but its a bit vague. My cars 1989 1800 Clipper, can you please tell me what engine code this is?
Thanks in advance, Robin.

i just order the complete head set,comes with every gasket you will need,and order the head bolts too,if its a gti it will be a Dx if its carb it will prob be EX

any mk1 1.8 or mk2 1.6-1.8 (petrol) gasket will be fine, gsf sell elring ones which are oem quality
