holley 4160 leak

all,
Please excuse if this a rerun. I may have posted earlier with same leak.

I am fighting a fuel leak on a Holley 4160 carb. The OEM fuel bowl was warped, and I replaced it. I am still getting fuel somewhere along the bottom of the front fuel bowl.
I discovered another leak around the bottom of the metering plate, where the factory drills out the passage for the accelerator pump. The metering plate had some sort of a pop rivet from the factory. I removed the pop rivet, drilled and tapped the hole, and inserted an allen set screw, along with some fuel resistant gasket maker. But I think it is still leaking around the set screw.

What kind of sealer can I use around the threads of the set screw, that gas won't destroy?

Thanks for your opinion

Something like this.

It just needs to be gas impervious!

Google it for different sources
