I did not try going over 35 because it pinged slightly and occasionally where I had it, which I was surprised about. Perhaps that will be alleviated after this cleanup.
And yes, I did verify the accuracy of the balancer after pinging so early!
Try rounding off all the sharp edges in the combustion chambers on the head now that you have them off. That may help with some of the pinging. Don’t go too crazy though.
