to start with Use Michigan 77 full groove brgs , Melling oil pump HPressure not High Volume
not sure what to do for a piston , the Speed Pro L2315F is a good choice with a closed chamber head
True roller timing chain , get the rotating assy Balanced ,
use a windage tray
replace the rod bolts with good new bolts , Pioneer or ARP etc
I use 1.81 exhuast valves in the heads ,
the rest depend on what you want , cam & intake have to match & it depends where you want the powerband, valve train is also dictaed by Cam choice
to be SCumakers has the engine mounts
