Check My Cam Degreeing
That method is used to measure installed centerline of the intake lobe (ICL). I am guessing that the 108 and 112 numbers you refer to are LSA (lobe separation angle) numbers. Those are are 2 different things. So are you looking for ICL, or LSA? Sounds like LSA, which is a different measurement.
As a side comment, if your ICL is at 98*, then that is quite heavily advanced for either cam version. To verify ICL, I'd repeat the measurements at .050" lift from 0 lifter lift (just because that is more standardly done) and compare. Make sure you are measuring at the lifter body, not the pushrod or lifter cup; the possibility of the hydraulic lifter being 'soft' when there is is no oil pressure is a good source of error.
