what you put on it depends on your budget and intended use

Have 1.94" intake valves (and 1.60" exhaust, if you feel like it) put in your 305 heads. Do basic pocket porting (aka "bowl work"). They will out-flow those 350 truck heads in a major way.
Comp XE26x cam. The truck engine probaby doesn't have the provisions machined for roller lifters - if so, a flat tappet version with lifters is in order. If the roller provisions have been machined, it probably still have flat tappet lifters, so you'd have to get new roller lifters and proper length pushrods.
Headers are always a good goodie to do.
