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
