Engine Works Circle Track Baffled Valve Covers

Engine Works offers Circle Track baffled valve covers for a variety of applications, including many Chevy small block engines from 1955 and up. These specialized, high-clearance engine covers are designed for high performance racing. They feature built-in baffling and tall breather tubes that effectively manage extreme crankcase pressure and prevent hot oil from splashing or "slobbering" out into the engine bay during intense, high-speed cornering.

Additional details:

* Built-in Baffling: Internal shields prevent flying oil mist and direct oil spray from reaching the top vent tubes, ensuring crankcase pressure escapes without causing spills
* Extended Breather Tubes: They include tall, welded breather tubes (often 1 3/8 in. or larger) typically positioned only on one side of the engine to suit oval-track applications
* High-Clearance Design: The taller "tall" profile allows for the use of larger camshafts, roller rockers, and stud girdles often found in Circle Track and race engines
* Durable Construction: Manufactured from heavy-duty steel or lightweight fabricated aluminum, featuring thick billet rails to prevent warping and ensure a leak-free seal under high temperatures
* Circle Track applications typically do not use standard PCV (Positive Crankcase Ventilation) valves because they can pollute the incoming air charge. Instead, these baffled covers allow the engine to "breathe" freely while retaining the crucial oil
* The steel covers are available in a natural or black finish
