I rebuilt the carbs throttle shafts and float pots all that stuff with a kit from Moss. One of the needle valves was DOA so I put the one on e back and it worked great. As I let the engine warm up and then tuned the carbs and shut the engine down I noticed a drip coming out of the drain in the front of the intake manifold and it was fuel any suggestions as the what is happening
I will replace the second valve in the float pot to start with because I don’t trust that it works any better than the other one but beyond that I am stumped

If it's not a sticking shut-off valve, it could be a leaking float in one of the carbs.
Take each one out and give it a shake, then if you can hear fuel rattling about inside it you know it's leaking and needs replacing. (Unless you're handy with a soldering iron)
I'm told the ethylene in today's fuel can eat away at soldered joints, amongst other things...

A way to check if the float level is correct is to remove the dashpots and pistons and look at the tops of the jets. The fuel should be visible just below the top of the jet (1/8" or so down from the top), if the float has sunk the fuel will be above the top of the jet and able to dribble into the manifold.

If the fuel level is correct, then you probably don't have a sunk float and I would check to make sure you aren't simply set too rich causing excess fuel to build up in the manifold.
