Question on BMW 3-Series E36 Camshaft Timing

I'm in the process of removing the head on my 95 M3. The car has the vortech supercharger and is running a water/meth injection system. The vanos was redone by the previous owner about 10k miles ago.Â*As I was trying to remove the vanos, I noticed that when I set the engine in TDC with the cam locking pin as well as having the marks line up on the block and the crank pulley, the cam shafts are 1-2 teeth more clockwise and the locking tool is not fitting. The car ran great prior to the failure of the head gasket with nothing to suggest the timing was off. Is it possible that the previous owner altered the timing on purpose? How should I proceed with the tear down, and should I keep the timing the same when I reassemble everthing? Thanks.

I would think it should line up. Unless the cam was timing for performance. I would check with the owner to see if that is the case before proceeding. My instinct would be to time it correctly.
