Product Details

Features

  • Tall finned aluminum covers suit big block Chevy valvetrain clearance
  • Baffled design helps control oil splash and reduce blow-by

  • Perimeter-bolt mount — confirm generation & bolt pattern before ordering

Description

These tall finned aluminum valve covers are built for Chevrolet big block V8 engines spanning three generations — Gen II (Mark IV) at 396, 402, 427, and 454 CID, plus Gen V and Gen VI at 454 CID — from 1965 to 1995. 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.

Since this cover spans three big block generations, confirm your specific generation and valve cover bolt pattern before ordering — design details can vary across generations even at the same displacement. This is a perimeter-bolt mounting style cover; verify against your cylinder head bolt pattern. At 3-11/16" external height, this tall design suits aftermarket roller rockers or taller valvetrain components — verify clearance before ordering. The 1.25" breather/grommet hole should match your breather cap or PCV valve neck size. Sold as a pair, with gasket, grommets, and mounting hardware not included.


Applications
Fits Chevrolet big block V8 engines: Gen II (Mark IV) at 6.5L/396, 6.6L/402, 7.0L/427, 7.4L/454 CID; Gen V at 7.4L/454; and Gen VI at 7.4L/454, 1965-1995. Common applications include Chevelle, Camaro, Nova, C10/C-K trucks, Corvette, Impala, Caprice, and big block Chevy street, strip, and rebuild builds.

Installation
Confirm your specific big block generation (Gen II, V, or VI) and valve cover bolt pattern before ordering — design details can vary across generations. Perimeter-bolt mounting style. Gasket, grommets, and mounting hardware are not included. Verify rocker arm clearance at 3-11/16" external height, especially with aftermarket roller rockers, and confirm your breather cap or PCV valve neck size matches the 1.25" breather/grommet hole.
