How much total advance?

So I have an '83 318 with stock compression, a MP 220*@.050 .455" cam and TQ on a performer intake. Car is a '70 Dart with O/D 4 speed and 2.94 gear. I am recurving the distributor and was wondering how much total advance to run. Motor is pretty happy at 22* initial and I am not running vacuum advance. I am running just the light spring and welding up the slots to limit total advance. So 32* to 38* is what I have seen recommended. My question is because I have low compression would the motor run better with more advance?
