We are still running the front metering rods. The car will be mainly a street car. We have kept our 69 Stocker engine but with a 2800 stall and only a 373 street gear in it now, but LOVE how the engine performs on the street

Sounds like a 1/8" air bleed hole through the primary throttle butterfly is about right. if you have the proper static initial timing, the engine's idle characteristics would improve to where no further mods were necessary.
