Yes, that's exactly what was required of the 7mm. If you didn't have a pin to fix the cylinder head back a bit, you would have to shim the front to keep it back. If you left it forward, the piston would rest too far forward, causing the sector gear to crash on to the face of the first tooth. It would snap shortly afterwards if the issue wasn't corrected.

I assumed it was fixed for 8mm, but I guess not.

they fixed it by including a thicker cylinder head,

below is mine from a silent piston set, compared to the one that comes with the prowin. http://img132.imageshack.us/img132/5...0118ye8.th.jpg
