Biohazard

Well I have 1 and 4 sorted out.
1. looks like a water neck gasket for a later 360?
4. looks like choke thermostat gasket for an engine other than mine.
#2 possibly a water pump gasket for a big block? and I have no idea for #3 but it is looking more and more like I don't need these - just afraid to toss something out by mistake and end up needing it later.
