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.

>>b3 kit raises and shifts the shaft...?<<<

Your in a pickle...that rest position looks to be where the pushrod needs the MOST clearance, as the rocker arcs up, the adjuster swings out pushing the pushrods out ever farther? kit looks to help minimize the lateral change in full sweep movement but seems to hurt in the static position of the pushrod. but if your still rubbing......carbide.
