What CR for Harley 103" kit

[BigD]

I have no idea how to calculate CR.  I had a 103" big bore put on when I purchase the bike a couple years ago, and have never taken the top end off.  Does anyone know what the CR would be for the BB?  I thought I heard somewhere it is a little higher than the stock 96" engine.  Thanks!  Your input is appreciated

 Just the big bore would change it roughly a half a point or a little more. Without knowing the actual deck hight, combustion chamber volume and head gasket thickness it would only be a guess.
