there are several different levels of a built block, to me a fully built block would be:
stripped down bare (block and head), then dipped in acid, then honed and level out mating surfaces
forged crank (unless the stock one is strong enough to hold your power needs) with chamfered oil passages
new bearings all around
forged, billet, or H-beam rods with new rod caps and arp rod bolts
forged pistons with new rings.
ARP Main bolts
Full port and polish on the head.
New/stronger and lighter valves
Stronger retainers
stronger springs
reground or billet camshafts
metal headgasket
that should do
