Hey James,

Ties, like beams and stems, vary widely in terms of aesthetic preference, and 
LilyPond offers a few properties to help express these preferences through 
various minima, maxima, and penalties.

Try setting:
\override Tie #'details #'outer-tie-length-symmetry-penalty-factor = #0

before your chords - I think this may be what you're after.

Here is a list of all the factors and their default settings :

                   (ratio . 0.333)
                   (center-staff-line-clearance . 0.6)
                   (tip-staff-line-clearance . 0.45)
                   (note-head-gap . 0.2)
                   (stem-gap . 0.35)
                   (height-limit . 1.0)
                   (horizontal-distance-penalty-factor . 10)
                   (same-dir-as-stem-penalty . 8)
                   (min-length-penalty-factor . 26)
                   (tie-tie-collision-distance . 0.45)
                   (tie-tie-collision-penalty . 25.0)
                   (intra-space-threshold . 1.25)
                   (outer-tie-vertical-distance-symmetry-penalty-factor . 10)
                   (outer-tie-length-symmetry-penalty-factor . 10)
                   (vertical-distance-penalty-factor . 7)
                   (outer-tie-vertical-gap . 0.25)
                   (multi-tie-region-size . 3)
                   (single-tie-region-size . 4)
                   (between-length-limit . 1.0)

We always strive to have the best out-of-the-box result possible, so if you 
feel after experimenting with these settings that you arrive at a result that 
is more akin to what you see in musical rep, send us a scan of the rep and the 
parameters you used to get there and we can start considering how to encode 
this (these) exception(s) in LilyPond's default output.

Cheers,
MS
