Some one will have to verify, but I am pretty sure it is 1.2mm

From what I have read somewhere (don't remember exactly where), that the stock head gasket was 1.2mm, then you can go to a 1.0mm to get slightly higher compression or go to 1.5, 1.8 etc to get slightly lower compression. But like I said...it may not actually be 1.2mm, its just what I remember reading.

I'm having a 1.2mm headgasket fitted when my car goes in to Rod Bellls, he said this was to lower the compression a little (over the standard head gasket) so i can up the boost a bit more, and that the standard gasket is also metal but 1mm IIRC
