The 814ce has had numerous bracing patterns over the years, each yielding differing results. You can read more about them here:
https://www.taylorguitars.com/guitars/acoustic/features/bracing. The years they were used are approximately:
Standard X: up through early 2003
Standard II (Forward Shifted): 2003 through early 2010
CV: mid 2010 through 2013
Advanced Performance: 2014 and up
Note that these bracing patterns are still used in the Taylor lineup today: Standard is used up through the 200 series, Standard II is used on the 300 through 700 series (except the new 600 series), advanced performance is used on the revoiced 600, 800 and 900 series, and the CV pattern is still used on the Presentation series instruments.
So essentially, the bracing pattern would be the same as the new 714ce on the mid 2003 through early 2010 model 814ce. Other years will feature different bracing patterns.
