Any way of knowing what valve springs we have prior to pulling (vin or engine numbers)

2014, 5.3, 4x4, work truck
 

Know way I know of but it’s not hard to pull the drivers side valve cover and take a peak.  Just leave the coils on the valve cover and pull the plug wires off the coil.  Then it’s like 6 or 8 bolt to take it off.  The cover on top of the valve cover just pops off

Great, thanks very much.

For comparison I just had the SV cam installed on my 2015 6.2. Dyno'd with E-85 with stock manifolds and intake.
