2009+ 5.7 Hemi Eagle

I've been following and learning from this thread a while. I am in the process of building an 09 eagle I bought at a salvage yard.
I will be using megasquirt ms3 that I had previously used on an 03 5.7 hemi. I have installed a 6.4 hemi cam with the compcams cam lock.
The problem I ran into is trying to select the correct valve springs for the cam I have. I've called Jeg's and was told their springs are only for 03-08 engines.
I purchased a subscription from Mitchell1Diy for an 09 ram and it gives a 1.81 inch valve spring installed height which is the same installed height as a 03 motor.
I tried as best as I could to physically measure the installed height on my engine with my digital calipers and came up with a reading of 1.94.
So now that leads me to believe I either measured wrong or the installed height spec on mitchell1diy is incorrect.
I would appreciate any input on this.
