The melting point of pot metal is 419 degrees. The melting point of aluminum is 660 degrees. Locktite's instructions say you must heat green locktite to 400
degrees to remove it. There is a good chance that heating the screws to the point of releasing the Locktite will bubble or melt the mount, along with any other low melting point parts.
The best advice came from Dave
. Drill out the screws and re-tap.
