I'm installing a stroked 2.8 (3.4L) right now, but i am not sure about something. Do i need to change the flywheel if i'm just using a stock 2.8 and using ARI's 3.4 stroker kit?

let us know how the engine does when you get it all done.

Usually a stroked 2.8 is a 3.1. A 3.4 has 4mm more bore as well as a longer stroke.
If the kit is a crank from a 3.1 or 3.4 then you need to have your current flywheel balanced. The only reason you can use your current flywheel would be if the new crank is weighted.
