340 Rebuild "Musts"

Picked up a standard bore '71 340 last weekend, and curious as to what you guys think is "absolutely necessary" on a build, and what is more along the lines of a "nice to have". I picked up "How to Hot Rod Small-Block Mopar Engines" but this book isn't exactly what I thought it would be - lots of talk about race engines, not a lot of talk about street engines. For this 340, I'm shooting for 400 HP and to bearable on the street.

Known about this engine: Standard Bore, Rod journals .010 under, Main Journals are standard, forged 4-speed crank, stock rods. The bearings look like some debris got in the engine. Not "Holy Sh*t" bad, but they definitely have some stuff in them.

Things I'm curious about:
Sonic Testing (Book calls it a "must"), Align Boring, Decking, Stock Vs. Aftermarket Rods, Aftermarket Rod Bolts, Replacing Bushings on rods.
