The port and chambers are carefully designed to provide the best combination of high flow capabilities and improved port velocity.

Following porting each head receives: Precision valve job to maximize flow & provide extended life, CC checking chamber size for correct compression, surfacing to insure deck flatness, professional assembly, setting spring height & checking all tolerances.

with retainers and keepers.
