• Specifically designed, high-performance, hard-anodized valves (OEM cannot be used).
• Features an aluminum cylinder head with a removable copper dome, allowing higher compression ratio and anti-degradation functions (unless otherwise stated).
• The kit also includes a Cast-Lite piston set with a flat top and a set of flanges for the upper part from Athena, which includes necessary sealing and connecting components.
• Direct installation; no matching required unless otherwise stated.
• Initial diameter, high compression.
