BRSUNAVOM Stainless Steel Small Block Chevy Bolt Kit — 211-Piece SBC Hardware for 265–400, Header-Clearance Washers

BRSUNAVOM's 211-piece stainless steel hex bolt kit supplies complete, corrosion-resistant hardware to restore and secure non-EFI Small Block Chevy engines (265–400).

This meticulously organized kit replaces and upgrades the visible and critical fasteners on SBC engines, combining durable 304 stainless steel bolts with specially sized washers to clear modern large-tube headers. Each group of fasteners is individually packaged and labeled for faster installation and inventory checks. The selection covers common wear points—from valve covers and intake manifolds to oil pans and timing covers—so you can give a classic Chevy a refreshed, corrosion-free appearance while maintaining strength under demanding conditions.

What engine models and applications does this kit fit?

Designed for classic small block Chevy engines, the kit fits non-EFI 265, 283, 302, 305, 307, 327, 350 and 400 engines. It targets replacement and restoration projects where factory-style hex bolts and stainless durability are preferred over stock hardware.

How does the kit handle header clearance and high-horsepower demands?

Header fitment is addressed with the included 3/8-16 x 1" Allen header bolts and specially sized small-OD, extra-thick washers that clear large tube headers. Fasteners are 304 stainless steel for corrosion resistance and high tensile strength suitable for hot, high-stress engine environments.

• Header bolts: 3/8-16 x 1" Allen head for secure clamping.
• Special thick small-OD washers to avoid tube interference.
• 304 stainless steel construction resists rust and maintains finish.

How will these bolts change my engine's appearance and maintenance?

Swapping original hardware for polished stainless hex bolts instantly refreshes the engine bay, creating a clean, uniform look while reducing future corrosion-related maintenance. Because the components are stainless and thicker where needed, they help maintain torque and clamping under heat cycling and repeated service events.

• Polished stainless finish improves engine bay aesthetics and resale appeal.
• Reduced corrosion means less seizing and easier future disassembly.
• Individually labeled packs speed reassembly and parts tracking.
