The 4 deg advance is ground into the cam or rather how they place the dowel pin.

All things being equal if you line up the timing marks (in the o keyway) in theory it will degree in at 106 but timing sets can be all over the place so the need to check.

Sounds like you are a mile out somewhere did you do .100 and .050 before and after max lift to get the installed centerline.

I do them opening and closing @ .050 and the before and after max lift helps you catch major screw ups
