In my opinion these true'd tip bushed rocker arms are a must have upgrade. These have bronze bushings instead of needle bearings and the tips have been true'd. The stock rocker tips without modification are not flat and will cause side loading of the valve which in turn will cause wear on the valve guides. Great product here, two thumbs up!
Place of Install
Install was pretty easy. I followed the oem rocker arm install procedure. This is important because it prevents you from tightening against the valve spring pressure, possibly messing up the aluminum threads in the heads. You want the lifter on the base circle of the cam for each rocker arm you torque down.
