The Summoner in my group just hit level 10 and evolved his Eildon to be sized Large, have two heads (one with 15 foot reach) and also have winged flight.
I am concerned in any indoor dungeons he is going to take up half the map and block the rest of the PC's from combat more often than not... and also having different attacks with different reaches will make things a bit of a nightmare... but that aside - any ideas on how I can deal with this would be appreciated.
My main question though - I cant find anywhere if there is a modifier for perception and stealth for a winged creature? He flys all the time - but previously his Eildon had magical flight - so it wasn't an issue.
I can just imagine - in a 20x20 foot room - a large winged serpent taking up 25% of the space in the room - flapping his wings to hover would make so much noise and distraction - air would be gusting out with every flap, blowing things around the room etc etc.
Being large gives it a -4 penalty to stealth.
I am unaware of any special rules regarding winged flight and stealth. You could give him another penalty to stealth or perhaps a fly check to keep the noise down. Both of those would be house rules, and the player should be part of any discussion.
In general, however, I wouldn't worry about it. LazarX is right. It would be very difficult for such a creature to be in a position to even make a stealth check.
As for the impractical size, that seems like a problem created by the player that will most likely only hurt the players, and therefore is for them to worry about. If the large eidolon makes it so only half the party can fit in a room, and influence the battle, it would be in the party's interest to fix that. I think the simplest solution, assuming its on the summoner's spell list, would be Reduce Person. I don't have the Summoner in front of me, but I believe they have that spell as well as Share Spells so he could pop the eidolon back down to medium for 10 minutes a casting.

Before you make any house rules, be aware that there are a number of winged animals (owls are a classic example; see also here) that are nearly noiseless in flight.
Thanks for the great suggestions!
I like the idea of a flight check combined with any stealth checks! I know he wont really be in a position to stealth - but when my players are moving in an area - say an adjacent room - and decide to move quietly - I have them roll stealth against the creatures in the adjacent rooms perception for hearing them - is this not the way I should be playing this?
I chatted with my player and he decided to make him medium size again with magical flight and take the the evolution surge, greater spell - so he can make him large with the spell for brief periods if required.

There is a difference between a tiny (by game mechanics) bird gliding through an open area filled with trees, and a large monster trying to hover in a tiny (from the perspective of the monster) room made of stone, presumably with a lot of small objects that are gonna be thrown about.
However if he is using magic, it's pretty moot.
