Valve Cover Hardware Kit Fits 68321 Covers

The MOROSO Valve Cover Hardware Kit (MPN 68905) is a complete fastener set engineered for small-block Chevy valve cover installation and secure retention. This kit supplies the precision-threaded bolts, washers, and hardware needed to properly mount 68321-series valve covers while maintaining vibration resistance and preventing fastener loosening under engine operation.

The kit includes eight 1/4-20 inch thread bolts measuring 4.750 inches in length, paired with matching washers and Allen head design for secure, tool-accessible installation. Black oxide coating provides corrosion resistance and a finished appearance, essential for engine bay environments where moisture and heat exposure are continuous. The 1/4-20 thread standard ensures compatibility with OEM small-block Chevy specifications, while the 4.750-inch length accommodates the depth and stack-up of valve cover gaskets and sealing surfaces without over-extension into the cylinder head.

This fastener set is critical for engine builders, restorationists, and performance enthusiasts performing valve cover service, gasket replacement, or initial engine assembly on small-block Chevy platforms. Proper hardware specification prevents oil seepage at gasket interfaces and eliminates the fastener replacement guesswork that often results in incorrect thread pitch or bolt length, both of which compromise seal integrity.

OEM-specification fasteners like this kit eliminate compatibility risk and reduce downtime during engine work. The eight-piece count covers both valve covers on a standard small-block V8 configuration with proper torque-down sequence capability.
