Product Description:
Hawks Motorsports is pleased to offer our clients the Chevy LS1/LS6 Up to 2003 Cylinder Head Stud Kit, Hex Head ARP, Part Number 234-4110. This ARP Pro-Series head stud kit is designed for Chevrolet Gen III LS applications using the early cylinder-head fastening configuration. The kit contains four short studs and sixteen long studs, along with hex nuts and hardened washers. ARP identifies 234-4110 for Gen III LS Series small-block applications from 2003 and earlier.
If you're building an early LS and already have the heads off, this is exactly the kind of hardware upgrade that makes sense to handle while you're in there. The 234-4110 uses ARP's 8740 chromoly studs with a hex-head design and the correct mix of short and long studs for the early LS configuration. For a street car, swap project, or serious LS build, upgrading the head fastening system gives the engine builder a purpose-built set of hardware rather than relying on the factory-style head-bolt arrangement.
The studs are precision centerless-ground and thread-rolled after heat treatment. ARP also supplies hardened, parallel-ground washers to help provide consistent load distribution at the cylinder-head fastening points.

- 1998-2002 Pontiac Firebird LS1
Hawks currently categorizes this exact 234-4110 product under its 1998-2002 Camaro engine components and LSX conversion categories.
Corvette Application
The kit is applicable to early Gen III LS configurations found in the C5 Corvette, including LS1 and early LS6 applications, when the block uses the early 4-short/16-long stud configuration. The exact engine configuration should be verified on engines from transition years.
IMPORTANT APPLICATION NOTES AND EXCLUSIONS
- 234-4110 is the hex-head version of the early Gen III LS ARP head stud configuration.
- ARP's current catalog specifies 4 short and 16 long studs for the 2003-and-earlier Gen III LS configuration.
- Do not select this kit based solely on vehicle year when the engine has been swapped or replaced.
- The actual block's cylinder-head fastener configuration should be verified.
- The early LS configuration uses different stud lengths; this is why the kit contains both short and long studs.
- 234-4316 is the corresponding early LS 12-point-nut version.
- 234-4317 is a different configuration for Gen III/IV LS applications using all same-length studs and is listed by ARP for 2004 and later applications.
- This kit is not for LS3 cylinder heads according to current application guidance.
- This kit is not an LT1 cylinder-head fastener kit. A 1997 Camaro or Firebird equipped with the LT1 does not use this LS stud kit.
- Do not assume that every LS-based engine from a given year uses the same head-stud configuration.
INSTALLATION NOTES
ARP's installation instructions for 234-4110 specify the following general procedures:
- Inspect all hardware before installation.
- Clean the block threads thoroughly and chase them if necessary.

- Clean the cylinder-head washer seating surfaces.
- Install the studs hand tight; the internal hex is intended to aid installation/removal and not to torque the stud into the block.
- Keep the cylinder-head and washer mating surfaces clean and dry.
- Lubricate the stud threads and bottom of the nuts with ARP Ultra-Torque Fastener Assembly Lubricant.
- Follow the ARP installation sequence and torque specifications supplied with the kit.
- Verify block and cylinder-head deck condition and gasket requirements before final assembly.
