Pushrod Rub (Intake side of head)

What did the b3 correction kit exactly do? Id feel comfortable grinding the pushrod hole with an accurate wall thickness measurement. What other options do you have...careful grinding is free.

Moved the rockers up and away from the valves. The pushrods would be fine without it, but the rockers come into hard contact.

I was looking for more clearance than enough to spin, but if that's enough then I'm probably ok.
