What should I do to the engine while it's out?

I didn't see the year, but it sounds like you have a dual row bearing. If so, I would recommend against the pelican kit as it is a single row bearing with a spacer. I would simply source a high quality dual row bearing over the internet and use that as the replacement. Bearings, like nuts and bolts, come in standard sizes. For my rebuild which is a single row I used the bolt from the pelican kit, and sourced a different single row bearing to work with a modified IMS.
