The gains found in lightening the rocker arms ar most very minimal. As TimT said. MOI is very small. The biggest change you can make to the valve train is in the valve and lifter pushrod side.
You can take the stock rockers and fit them with needle bearings for a decent upgrade. You really won't see much in the way of HP improvement, but the "rev-ability" of the engine will improve as will heat going into the oil. One thing that many people over look is camshaft design. That is one area where our engines are at a major disadvantange. When we start "lofting" the valves over the nose of the cam we really haven't gotten into anything exciting. |
