Featuring 105-pound valve springs and a 5-axis CNC port job, this head significantly boosts intake flow from 155 CFM to 220 CFM, improving low-end performance, reducing boost pressure, and lowering EGTs. Built on the foundation of the HP Reman Head, it includes new bronze guides, oversized hardened seats, and a high-performance CNC valve job for enhanced longevity and efficiency.
