1. I would not want a lump of RTV Silicone to come loose inside the intake port, and make it's way into the cylinder. The RTV Silicone will be exposed to manifold vacuum, significant air velocity pulses, and gasoline (liquid droplets, and vapor.)
2. Most RTV Silicone is not compatible with gasoline. Gets soft, degrades, loses integrity.

Under the "Instructions" tab:
" NOTE: Not for use as a head gasket or on parts in contact with gasoline."
The sooner you remove the RTV Silicone, the better.
How deep is the rocker stud hole below the actual rocker stud? Can you thread the hole the full length, and then screw-in a brass or aluminum set screw into the hole from the bottom, sealed with Loctite thread locker AND LOCTITE "ACTIVATOR"?
If this were me, I'd go back to using Loctite 592 thread sealer on the rocker studs,
and the aforementioned activator. You tried the sealer before, but not with activator. Probably wouldn't need the set-screw with this method.
