Ford Small Block Chrome Steel Valve Covers

• Chrome-plated steel construction for classic durability and engine bay shine

• Internal baffling helps control oil movement and reduce blow-by

• Fits Windsor 260/302/351W only — not compatible with 221 or 289

• Tall pent-roof-clearance profile for rail-style rocker arm applications

These valve covers are built for the Ford Small Block Windsor V8 — specifically the 260, 302, and 351W CID versions. This casting is not compatible with the 221 or 289 CID engines: mid-1966 introduced rail-style rocker arms that require a taller "pent roof" cover, and early 289s using the shorter pre-1966 profile will not clear correctly with this cover. The 255 CID (1980–1982) is not listed by the manufacturer for this casting and should be treated as unconfirmed rather than assumed compatible.

Construction is chrome-plated steel with a plain top style and a 3 3/4 in. tall, pent-roof-clearance profile, using a perimeter-bolt mounting pattern. Internal baffling is built in to help control oil movement and reduce blow-by.

Common applications include Ford Mustang and F-100/F-150 (302/351W years, 1968–1985) and Mercury Cougar (302/351W years). These covers are sold as a pair without gaskets, grommets, or mounting hardware, so those should be sourced to match your specific application.

Applications
Fits Ford Small Block Windsor V8 engines: 260, 302, and 351W CID only. Not compatible with 221 or 289 CID due to a valve cover profile change — mid-1966 rail-style rocker arms required a taller pent-roof cover, and early pre-1966 289s use a shorter profile that won't clear. 255 CID (1980–1982) is not listed by the manufacturer for this casting and should be treated as unconfirmed. Common platforms: Ford Mustang and F-100/F-150 (302/351W years, 1968–1985), and Mercury Cougar (302/351W years).

Installation
Covers use a perimeter-bolt mounting pattern at a 3 3/4 in. tall, pent-roof-clearance height. No gaskets, grommets, or hardware are included. Confirm your engine's rocker arm style (rail-style vs. earlier stud-mount) before ordering, since that's what determines pent-roof clearance compatibility.

Does this fit a 221 or 289 Windsor engine?
No. These valve covers are designed for Ford 260, 302, and 351 Windsor V8 engines. They are not compatible with the 221 CID Windsor or early 289 engines that use the shorter pre-mid-1966 valve cover profile. Beginning in mid-1966, Ford introduced rail-style rocker arms that require the taller pent-roof valve cover design used by this casting.

Does this fit the 255 CID Windsor (1980–1982)?
The manufacturer does not list the 255 CID Windsor as a compatible application. Compatibility is unconfirmed and should not be assumed without verifying the cylinder head and valve cover specifications.

What material are these valve covers made from?
These valve covers are manufactured from steel and feature a durable chrome-plated finish for corrosion resistance and a classic appearance.

Is this cover baffled?
Yes. These valve covers feature internal baffling to help control oil movement inside the valve cover and reduce the amount of oil reaching the breather openings during engine operation.

What does "pent-roof clearance" mean for this cover?
The pent-roof design provides the additional internal height needed to clear the rail-style rocker arms introduced on Ford Windsor engines beginning in mid-1966. At 3-3/4 inches tall, these valve covers offer the clearance required for those later valvetrain components and are not intended for the shorter pre-mid-1966 289 applications.

Do these come with gaskets or hardware?
No. These valve covers are sold as a pair only. Gaskets, grommets, breathers, and mounting hardware are not included and must be purchased separately to match your specific application.

Will these fit a 1968 Ford Mustang or F-150?
Yes. These valve covers fit 1968–1985 Ford 302 and 351 Windsor-powered Mustang, F-100, and F-150 applications equipped with compatible Windsor cylinder heads using the standard six-bolt valve cover pattern.
