Default S3 Cylinder head does not fit

Hello,
I bought a S3 cylinder head for my 1998 Gasgas EC250, but it is too big. On the website it said "fits from 1998-2017". The Bolt circle on the S3 head is 95mm. The one on my cylinder is 88mm. I did not really find something online, but may my bike have a 1997 motor? It also has the balancer shaft.
If so, can i get the S3 head for a 1997 motor? I really want it, but i dont want to buy a new cylinder (but the cylinder would interchange between 97 and 98 onwards, right?)
