He's talking lobe separation angle. Cam lift doesn't matter, although duration would. All specs identical, if you had a cam on a 110 lobe separation installed at 110 intake centerline, it would have less compression than a 108 lobe separation installed at 108 centerline. If you advanced the 110 LSA cam 4* to a 106 installed center line (ICL), the 110 LSA cam would have more compression.
