Valve covers have undergone quite the transformation over the last 60 years and are an underrated part of any late-model engine build. Gone are the simple sheet metal stampings with a few wire hold downs tacked on. While they used to be exactly as their name indicates (covers for the valvetrain), many valve covers are now also home to ignition coils, plastic engine dress-up pieces, and miles of wiring.
Holley’s latest are the Sniper Gen III Hemi valve covers, available in anodized silver (part #890015) or black-coated (part #890015B) finishes with a laser-etched “Sniper” logo. They “lend a high-end look to any engine bay without a high-end price,” Holley’s news release states. Bolt-on applications include the ’06-’19 5.7L, ’05-’10 6.1L, and ’11-’19 6.4L Hemi engines. However, they will fit the ’03-’05 5.7L’s if the ’06-later coils are used.
Carved out of 6061-T5 aluminum sheet then carefully TIG welded, they’re plenty sturdy enough to hold your high-powered coils and look the part while doing it. The flange is 1/4” thick and CNC machined for proper sealing all the way around. If you’re using custom rockers, the 2.25” overall height should help with clearance. Also included are rubber valve cover gaskets, mounting hardware, and spark plug O-rings. Covers are available in the same black (part #68501BG) and silver (part #68501G) coatings but without the “Sniper” logo under the Mr. Gasket brand name.
