Layover at Heathrow

(English is not my first language. Apologies in advance for any grammar mistakes!)

I am flying to LHR from Dublin with Aer Lingus at 19:20 (Terminal 2) and have an Aeroflot flight leaving for Moscow at 22:45(Terminal 4).

They are on different tickets so I have to go through custom (I am from non-EU country) and recheck my bag.etc

Is 3h 25m enough for this?

I have another connecting flight with Aeroflot in Moscow so I have to take the flight to Moscow on time...

Should I change the flight with Aer Lingus?

According to Heathrow's own connection planner, the minimum connection time between these two flights is 90 minutes. Since you have 3h25m you'll have plenty of time (I ran the simulator with random dates, but the flights should be the correct ones):
