Lifter preload doesn't take camshaft lift away.
TP has a very good tip. Check the rocker arms for binding, both on the pushrod side and the valve spring side. I've had several combinations where the pushrod would rub the rocker on mock-up. If the rocker doesn't hit the spring at closed valve position, it won't rub on open valve position.
