Id assume this is pretty well worked out, what is generally the most ideal intake and exhaust cam positions at say 4000-5000-6000-7000 rpm for a bolton car with a 2018+ manifold? Or with the higher rpm shorter runner manifold?

My experience has been to push intake to -20 from 2000 to about 4000. 5000 is a crossover and doesn’t make much difference either way. Then retard to about 15 by 7500. Exhaust doesn’t affect it that much. 15 works well enough. Maybe advance to 10 after 7000.
Arent the numbers referred to differently for Gen1 2 and 3?

Yes I am referring to gen2/3 timing.
