biggest lift cam with stock heads

Replace locks and retainers with the springs... you can usually get them as a set anyway. That way, you KNOW they will work.
Lumpy idle from the cam generally implies a cam that is designed for higher RPM power than what you are looking for. (and would be a really poor match for the kegger intake.)

Put the chevy catalog down and read the posts above this one.
Stock springs are beehive so you will need new retainers, locks are cheap, and might as well do valve seals too.
Lope at idle comes from tight lobe seperation & large duration...You don't have the mods to support much lope. Be forewarned, more than one engine has been roached by guys runnig stronger springs andhaving the stock two piece valves breaking.
Cams require soooooo much more than just the cam.

EDIT: Do you have a game plan in place, bad idea to just toss on some parts in a random order.

The setup I outlined in my first post is the most aggressive and reliable setup you can go with on stock heads with minimal supporting mods.
Magnum top ends aren't like cobbling together an SBC... Roller cams require different spring pressures than those Summit knock-off flat tappet springs you're looking at. Is $50 really going to kill you for a set of the right springs? That's already dirt cheap. You HAVE to replace the retainers, the stock retainers will almost drop through the new springs. Locks you can reuse, but they are so cheap why would you chance it?

all mods by the time I'm done are:360 block, cam, clearwater monster heads, 1.6rr, dbl timing set, 4bbl carbed intake, 670 truck avenger, headers, dizzy to match my msd 6a box, shift kit, converter to match my set up and 3.90 gears.

Manual or auto trans? If you have an auto.... you are going to need to do something for the electronic controls...... If the PCM doesn't have a clue what the engine is doing..... it isn't going to know what to do with the trans either.
Switching to a manual trans would solve the issue though.
Other problem becomes the Instrument cluster.... most of which is driven by.... you guessed it.. the PCM. You would need to do something about all of that as well.
