Not necessarily. If something prevented a valve from opening it could certainly cause a problem with the rocker arm. That "something" that prevented the valve from opening could be a piece of a broken piston. So while a broken rocker arm doesn't NECESSARILY mean that there is a problem with a piston, it's certainly something to cause concern.
You have to much lift on the camshaft lobe, They make a long slot rocker arm that looks like a stock rocker arm but it will not cut into the stud. The slot is where the rocker arm fits over the stud. If you are not haveing coil bind problems with the valve springs are broken springs then you can keep the cam that's in it and just use the long slot rocker arms are roller rockers to fix you problem.
