Common Usage: Mild street performance to mild race
Key Benefits: Minimal maintenance, little or no valve train noise and economical cost
Limitations: Long-term wear, limited rpm range, lobe profile limitations
Common Usage: Moderate street performance to serious race
Key Benefits: Increased engine rpm and profile aggressiveness vs. economical cost of hydraulic flat tappet
Limitations: Long-term wear, limited rpm range, periodic valve adjustment required
Common Usage: Serious street performance to all-out racing
Key Benefits: Maximum performance, reduced friction, most aggressive profiles
Limitations: Increased cost, periodic valve adjustment required, not well suited for extended low rpm operation
