Since you say that vacuum isn’t a concern and it’s a custom grind, maximize your investment and use the 128 cam formula and set the LSA on a 103. This gives you 78 degrees of overlap vs the MP 60 degrees of overlap. When you email or talk to Ken, he may give you an updated list with a different cam number.
