IMS Gen III HEMI valve covers are machined from solid billet bar stock for maximum strength, precision, and sealing integrity. Designed for Gen III HEMI engines, these billet valve covers combine OEM-style functionality with high-performance CNC-machined construction for engine bay appearance and durability.

These Gen 3 HEMI billet valve covers are engineered to clear any rocker assembly on the market, making them compatible with a wide range of stock and aftermarket valvetrain setups.

All sealing surfaces use factory-style O-ring gaskets to ensure reliable, leak-free performance under high heat and pressure conditions. Each cover features multi-location breather and fill ports for flexible crankcase ventilation configurations.

Each set includes a -12AN adapter and a block-off plate for simplified plumbing options. Covers are available in raw billet aluminum, clear powder coat, or black powder coat finishes. Despite their heavy-duty construction, each valve cover weighs only 4 lbs.

This item is proudly designed, engineered, and manufactured in house at IMS.
