After doing some more reading i think i confused myself on lsa vs centerline. Based off my cam card and the method im using i believe you are correct and i need to only retard it 2 degrees from the original 102 to get to the 104.
You can go in at 108 if you want, but it will be technically 4* retarded from where Cam Motion wants it. 108 will shift the torque curve up.
As a general rule, Cam Motion usually calls out a 4* advance from LSA. Usually. I had one cam ground on a 109 that went in at 109 but it was a weird combo. 104 will probably be better for what you want.
