Stock is a 7 hole. I'm not sure of the hone size. As for other injectors, some are custom made by various different companies, and some are other tips that have been modified. The schied 6x.012 are I believe a modified tip from a mack application. But many companies use a stock blank and EDM a new hole pattern into them. 8 holes are also common. There are other factors that play into the injector function as well, pintle lift, internal fuel gallery modifications etc... I'm really not too up on those though, so I can't tell you what the differences are.
