Machining recommendations 440

I have a 440 from 1973 that is stock bore, steel crank, six pack rods, stock pistons.
We are planning to put a stroker kit from 440source in it to make it 500 ci.
Since we will be replacing the entire rotating assembly I wanted to know what machining operations you recommend before that. I know I have to hone and bore cylinders. I should have the block magnafluxed as well. What about line boring the crank journals and camshaft bearing journals? Is decking needed or recommended? What do you look for in a machine shop?

I have mine zero decked, stud the heads and mains and line hone, Magna flux
