intake valves

Hello all

i have a few questions about my intake valves.

i found out one of mine is bent.

so im going to replace it…

i took it out and used calipers on it.

it is a 37mm valve.

is this a stock valve?

should i replace both of the intake?

should i replace the other ones too..

when i replace the valves do i have to buy new shims to do the valve adjustment?
