I'm not too sure if this is suppose to happen, but are roller rockers suppose to move side to side? I started inspection stuff really close today and happen to wiggle the rockers. They make a clicking sound when moved side to side, but are tight and don't have any play up and down, is this normal? I also noticed on the #5 cylinder that the rocker on the exhaust side was hitting the valve cover cause of its movement side to side.

If the rockers are bad and I get knew ones, would 1.72 rockers work on my car with the stock heads and E cam?

Thanks all, Craig
