I am looking for a rubber or like material that can have a flame very close and 350+ temperature resistance that could be used to seal a glass or metal bottle with flammable liquid inside. It would be exposed to these levels for up to 1hr and repeatedly.

Silicone is a good idea for lots of things and I will be using it else where in the design but I had been informed that silicone is not solvent/ fuel safe. Can anyone clarify?

Very High Temperature Effects
At temperatures above 316°C, the typical pattern of heat aging changes. Elongation may not decline as fast as the tensile strength of Silastic® silicone rubber. Hardness, which is normally increased with aging at moderate temperatures, may actually decrease with aging at very high temperatures.
The table shows the effects of temperature on silicone rubber service life, measured on a stock that is especially compounded for stability at extreme high temperatures.

Silicones can take that sort of heat and offer chemical resistance as well

Look for oven supply stores.
