Product Details

Features

  • Finned aluminum covers add classic styling to Pontiac V8 valve covers
  • Baffled design helps control oil splash and reduce blow-by
  • Fits Pontiac V8 301-455 CID, 1957-1981
  • Sold as a pair — gasket, grommets & hardware not included

Description

These finned aluminum valve covers are built for Pontiac V8 engines from 301 to 455 CID, spanning 1957-1981 applications. The baffled design helps control oil splash and reduce blow-by, while the finned top and polished finish give the valvetrain area a classic, finished look.

At 2-3/4" external height, verify clearance with your rocker arm setup, especially if you're running aftermarket roller rockers or taller valvetrain components. The 1.25" breather/grommet hole should match your breather cap or PCV valve neck size. These covers are sold as a pair, with gasket, grommets, and mounting hardware not included — plan to source those separately.

If you're fitting these to a 301 or another small-journal/economy Pontiac variant, verify your block's main journal size and deck height before ordering, since this cover is built for the 326-455 CID engine family specifically.


Applications
Fits Pontiac V8 engines: 4.9L/301, 5.3L/326, 5.7L/350, 6.4L/389, 6.6L/400, 6.9L/421, 7.0L/428, and 7.5L/455 CID, 1957-1981. Common applications include GTO, Firebird/Trans Am, Catalina, Bonneville, Grand Prix, Le Mans, Ventura, and Tempest.

Installation
Perimeter-bolt mounting style. Gasket, grommets, and mounting hardware are not included. Verify rocker arm clearance at 2-3/4" external height, and confirm your breather cap or PCV valve neck size matches the 1.25" breather/grommet hole.
