It all depends on what you really want to do with it, and how much you want to spend.
A good "freshining" rebuild would suit most needs. Unless you are going to change the heads, even a small cam is a waste of time IMO. The heads are very limited in stock form. And the stock castings are prone enough to cracking, that porting the stockers is a potential waste of time as well.
The biggest changes that I could recommend to you would be the following:
M1 2bbl intake. This gets rid of the leak prone factory beer barrel intake. Not a cheap manifold, but worth the price.
Ported stock TB or a billet 50mm TB. Many places for these, helps getting the air in.
1.7 Roller rocker conversion. I would say go with Harland Sharpe non adjustable's, as they are pretty much a bolt on and go setup, and will help build a little more torque
Headers will help, but are not a must.
To get the most out of the current setup, I would recommend a SCT tune. This can get even more potential out of your current combo, and will help maximize the benifits of the above changes.
That list will add 40-50 ftlbs of torque across a pretty broad band, and make the truck drive much better, with more reliable long term performance, and give nothing up in terms of longevity.
