Our custom VAC/ARP S14 Head Bolt set is made exclusively for VAC to meet OE Spec and beyond.
Per our request, ARP designed and manufactured these Head Bolts to be direct replacement for the OE S14 Head Bolts.
These bolts can be torqued to OE Spec using the OE Torque Pattern and provide the same ease of mind that the OE S14 Head Bolts would provide.
In addition, our VAC/ARP S14 Head Bolts can provide additional torque for those wanting to clamp their cylinder heads down beyond OE torque in forced induction applications.
- Fits all S14 engines & displacements, including the S14B20, S14B23, S14B25, and S14B27 and any other configuration that uses the OE Head Bolts.
- Complete Set Of 10 ARP Head Bolts
- OE Size 12 Point Head Design
- Uses OE Washers (Not Supplied)
- Does not require re-torque of cylinder head after heat cycle
