The first ModS cam closes the intake valve at 52deg ABDC
While the second closes the intake at 65deg ABDC
If you do not up compression when using the more aggressive 2nd cam you won't like the results. The 2nd cam at 65deg ABDC will not have enough dynamic compression to achieve peak torque.
I also suspect it will not work well on a static compression of 10.3:1 but the first cam with 52deg ABDC should do OK at 10.3:1
The 65deg ABDC cam needs more compression to achieve a decent level of dynamic compression.
When you select a cam it's very important to select the correct static compression for that given cam.
