Mike, you are breaking in your new engine, right. I'm sure it will give you even better performance as it wears-in.
That 52-psi is just fine, and you're right, ~60 would be my max.
Some things are well worth sacrificing gas mileage for. Detonation from running too lean is tops on my list. These carbureted engines aren't computer controlled, so our settings may stay the same, but the weather changes. Some days your engine will run sweet. All we can do is tune our adjustments within safe limits, then let it go.
Glad you set your oil pump up right. Extra lubrication will pay off big dividends in the long run.
