Tearing apart hemi 5.7, machine work worth it?

I'm sitting here trying to figure out what to do.
1. Dissabemble, machine work (bore), new internals? + $2000 in hotwire electronics
2. Get a block (cost alot btw) from something like jegs, then build? + electroncs
3. Step 1 + moparperformance conversion kit?
4. Step 2 + moparperformance conversion kit?
5. Buy a crate from mopar performance that is ready to go (lotta money)
