The gasket has 10 holes so no more than 10 but I think 1 or 2 are just guide pins or something.
I had issues just recently with finding the correct gasket, there are actually two types, 10 hole and 11 hole gaskets. My SC300 had 11 hole gasket and the 10 hole gasket that came with the pump was way off and wouldn't align with water pump. I only know this because I just replaced my water pump a few weeks ago!
