Building my 273

I have just pulled the drive train from my 1966 Barracuda and I'm trying to figure what I should have done to the engine for this build. This 273 is a two barrel / 180hp engine, and I'm looking to give this engine a mild build. Nothing over the top because I want to keep it towards the stock side but give it alittle get up and go at the same time. I have gotten a edlebrock 600/1604 carb. I have a factory steel four barrel intake, Mopar performance electronic igntion.
I'm planning on having the heads redone, a mild cam, and all new rings and bearing along with a new timing chain and gears.
Am I missing anything?
Any suggestions with regards to the cam size or head work or block work?
Some people have said a 600 edelbrock is to large for this engine.
