Description

Benefits: • Quicker opening lobe profiles deliver increased responsiveness & more area under the lift curve • More vacuum allows a step up in duration for greater performance • Best seller; excellent all around performance in street carbureted applications Important Considerations: • Work best with COMP Cams® roller rockers and matched valve springs • Require other performance parts (intake manifold, headers, etc.) for best performance
