Holley 650dp

I am rebuilding my Holley 650dp, Model 4777-2. I have everything back together except I am puzzled about one thing. Can someone tell me what should be UNDER the squirters in the Primary and Secondary? When I disassembled mine, Under the Primary side, it had nothing. Under the Secondary side, it only had a small metal cylinder type thing with a tapered end. Should both sides have this? Also, should there be a small ball also to go either under or on top, or both, of the small cylinder valve thing?
Oh yeah, also the seconday metering block does not have a power valve? It is factory blocked off. Maybe wrong metering block? I am not sure, it came this way on the car.
Thanks in advance for anyones help.

Got it. You can remove pic now. Thanks !

I just rebuilt (2) 4776-2 carbs (600 dp) and both primary and secondary had the metal cylinders under the squirters. I didn't have any ball or spring or anything under the squirters. I think that might be for newer models. -3 or -4 perhaps.
