Default OS12TZ Bearings

I bought some new bearings for my OS12TZ, I need to remove and install the new bearings for my engine. I noticed that OFNA makes a bearing remover kit....10797 10mm - 11mm & 10798 13mm - 14mm. I am thinking about purchasing one of these kits, I just need to know which one do i use for my engine....

just heat the block to 350 degrees for 15 minutes and then just tap the block on a wooden block. The front one will be a little harder than the rear bearing, for the front one get a wooden rod thats bigger than the hole on the bearing and push it out. Works every time. Do the same when you have toput the new ones in.

I use a flat-head screw driver thats bigger than the front bearing hole to gently push the front bearing out of the block. And as nitrodude suggested, just tap to get the inner bearing out.
