So as some of you have read earlier I have a noise after last night. I'm convinced its the infamous head tick after listening to a stethoscope of the valve cover. My car although has 84,000 miles. My question is should I just throw new valvetrain in the heads or buy ported heads with cams. I'm betting its the lash adjuster. While I have it apart should I just rebuild it? I'm going to put a twin screw on this winter. I'm just looking into other people's opinion in to this.
