CNC Head Porting — Single Head

CarmaPerformance Verified independent store

→

Flow-optimized port work on one cylinder head. We use a CNC mapping process that produces consistent flow numbers across all runners — not a hand-port job that's brilliant on one r unner and average on the others. Includes: CNC porting per our proven program for your engine family, flow bench data sheet, valve job if the seats need it (extra cost), and inspection report. Turnaround: 2-3 weeks typical, faster if scheduled in advance. For V-engines or boxer engines, see the CNC Head Porting — Pair SKU for a discounted bundle. Show more
