All VAC cylinder head services are performed on existing customer cores. This requires the customer's core to be supplied to VAC for servicing.
If you do not have a core, contact our sales team at Sales@VACmotorsports.com to have one sourced.
VAC's Stage 1 Performance Cylinder Heads are always a popular choice when rebuilding an engine and a fantastic value in performance.
