What a coincidence as I installed the 2L oil pump on my Stroker the same day
and ran into the same situation. It is a tight interference fit and I got
nervous installing it. As Stan said you need to use studs BUT unfortunately
the shop took them off the block and now can't find them.
What I did use were the shorter studs from the head and cut some of the
threads off - it worked like a charm providing you have extra studs. The
other alternative I also thought about was using longish bolts and then
cutting off the heads.
Hope this helps.
BTW, should I load up the oil pump with oil before fitting it?
