When you guys install new plugs do you put anti-seize on the plug threads? It does not look like the factory put any on them (original plugs)

Factory installation likely did NOT utilize Anti-Seize.
I do, however, recommend utilizing a good quality anti-seize on the threads when installing replacements.
Use a 12-13" piece of fuel line to thread the new spark plugs into the openings (helps to prevent cross threading).
VERY IMPORTANT: These spark plugs MUST to be TORQUED with a TORQUEWRENCH to 20 ft. lbs.
