bolt them on their the same
The 83 Chevy C10 comes with a 305 but not a 350. The 350 is an option on the 3/4 ton but not the 1/2 ton.
Yes it will. If you have the know how.
yes
valve cover gasket
YES

usally about 8 or 10 degrees BTDC will work fine to get it going.
The 83 engine will not work. You need a TBI / throttle body injection engine from 1987 to 1995. then everything will bolt right up and work just fine.
