I'm trying to bring back to life a Farmall B. I've got 2 new sleeves and 2 used sleeves that's looks like new. The used sleeves are 1/8 inch longer than the new ones. Does anyone think this will matter?

No. Should not matter.Just make sure everything clears.I would however put them on oppisite throws of the crank.My 706(D310) has a similar situation. I replaced a cracked sleeve with a used one from a cotton picker.It too was different/longer. Been there for 30 years and 5000 hhrs.
 
How long they are should not matter but if the bore is not the same then you will have problems due to an unbalanced engine
 
If there are on oppisite throws of the grank,no problem on a slow revving engine.Buddy's Big 4 has 2 aluminum and two cast pistons. runs smooth as glass.Used to have 3 aluminum and one cast,'jumped' around a bit,but had been like that for(50/60/70/?) years.Several years ago a neighbor put a 4" piston in an M.The other 3 were 3 7/8.Still running. While not really "approved",a guy can get away with a lot of stuff if needed.
 
No but is the bore the same thats what is important. If you need some good used ones i would have some but check the bore for wear ect. A good hone and some new rings will last a long time as you aren going to far all day with it anyhow.
 
Ya some time you can get by but other time that is enough to break a cranks shaft which I have run into before and boy does it hurt when half that crank shaft comes out and hits you in the foot. BTDT
