Hawks Motorsports offers our clients this 434-8002 GM Gen III LS Oil Valley Cover Bolt Set, Polished Stainless Steel, 12-Point, ARP for Gen III LS valley cover applications. This set features corrosion-resistant polished stainless steel construction, 12-point heads, and precision-machined fasteners designed for proper thread engagement and consistent clamping of the valley cover.

If you're building an LS and already have the intake off, there's no reason to put a bunch of beat-up factory bolts back on a freshly detailed engine. The 434-8002 set gives the top of the block the polished hardware it deserves, with 12-point heads that look right at home on a clean LS build. It's one of those small details that won't make the dyno sheet any bigger, but it definitely makes the engine bay look like somebody cared about the build.

The kit includes 10 polished stainless steel 12-point bolts for the GM Gen III LS valley cover. ARP incorporates a wide-area flange for load distribution and precision-rolled threads for consistent torque loading. Hawks Motorsports specifically identifies this 10-bolt configuration for Gen III LS engines and notes that Gen IV LS valley covers use 11 bolts.

• Verify thread engagement and bolt length before final installation.
• Clean the valley cover and block mounting surfaces before installation.
• Inspect all threaded holes for debris, damage, or contamination.
• Stainless steel fasteners should be installed with appropriate anti-seize to help prevent galling.
• Use the appropriate torque specification for the specific LS valley cover and engine application.
• Do not overtighten the fasteners, as excessive torque can distort the valley cover or compromise the gasket seal.
• Test-fit the complete set before final assembly.
• Verify fitment before installation when using aftermarket valley covers, modified blocks, or non-original engine combinations.
