Google is your friend. Do some homework.

Are the main caps there? 4-bolt or 2-bolt mains? How many drain plugs on the side of the block?

Whoever does your machine work should know how to drill the holes in whatever head you choose, if they are not present. For a street motor, definitely get them drilled. Run a good head gasket and make sure the deck and head surfaces are in good shape. Before you spend your first $1, make sure the block isn't already overbored. Stock bore is 4.125, 4.155 is typical 0.030 over. Beyond that is kinda risky and probably not worth your time and $$$. Then make sure the block isn't cracked and go from there.

You shouldn't need a forged bottom end for a street oriented N/A build....Cast crank (eagle/scat), good set of stock replacement type rods (5.700 rod length I-beams) and good machine work and assembly you'll be set.
