Put needle valves between your manifold and your burners. Pump your manifold at fill blast from the tank/source, adjust flame from the needle valve.

I just got done with my stand single teir with the bg14s and I used an adjustable regulator from amazon and gas balls valves from home depot and it runs great. The regulator to me was most important because once I got it adjusted right the burners looked great.
Here is a pic with them all going. The middle burner is a smaller banjo burner.

I use gas ball valves rather than needle valves and I can control the flame on mine with no issues. Although when you adjust its a subtle turn, my burners run great.

Mine are about 4 inches from the bottom of the keggle. I have three pieces of steel around the burner for the heat shield. I put a fourth one but it was starving the burner.

Do you plan on using low pressure or high pressure? I used heat shields because it made mounting my burners easier.

Do you have welded or weldless fittings? When I was using mine the front got really hot even with shields.
Do you have a pic of your build so far?

needle valves are made for regulating gas flow. ball valves are not meant to regulate flow, though they can be made to. just be aware that when you start using things in ways they werent intended, it can have unintentional results. like a 5 degree turn of the handle on a ball valve can be the difference between full on and full off.
also, because of the way ball valves are designed, its possible for them to cause explosions in gas systems when they are used for flamable gas metering. its highly unlikely at the pressures that we are talking about, but the sharp edge of the ball when only opened a small amount, coupled with a sufficiently high flow rate can cause heating. heat can ignite flamable gas. again, unlikely, but not impossible.
long story short- if given an option, use a needle valve to meter gas.

I agree that needle valves are the better choice, but I find the explosion thing dubious. How would the gas explode in the absence of oxygen? Is this a documented occurrence?

EBay is where I got mine, be prepared to pay a bit for them though. Totally worth the price.

Needle valves are far superior to ball valves for controlling gas.

I got mine from watercannon.com for less than $20 each. They are listed as chemical metering valves. They also have great prices on stainless quick connects.
Here is how we setup our stand:

I prefer a manual controlled propane setup like this:
1) 0-30 gas regulator to manifold
2) manifold to ball valve (for on/off)
3) ball valve to needle valve (for gas flow control)
4) needle valve to burner/pilot lights

Where to buy needle valves
audger is correct about needle valves... we use them on our multi-jet systems also and they work excellent
