360 valve stem seals

Hi everyone, building my first 360 & I got the fel-pro kit for all my gaskets. I was wondering why there are 3 types of valve seals in the kit. I think the one on the right goes on the exhaust valves? But I’m unsure if both the ones on the left go on the intake valves. The heads I got with the block were bare so I don’t have an idea of how they go. Any info would be appreciated.
