440 damper timing marks not correct

The old Summit spec and another I found both list 110 as intake lobe CL.
My measurements on the degree wheel at .050 lift on the intake lobe are 149.5 and 64.5. Added this is 214. Divided by 2 this is 107. So i need to move to 110 is my assumption. Just trying to verify.
Calculating LSA from the the spec doesnt match. 116 ex cl + 110 int cl is 226 giving an lsa of 113.
When it cools down in the garage I am going to measure BTDC and ABDC and use the formula to give actual centerlines and measured lsa. should be interesting.
