Product Details

Features

  • Finned aluminum covers add classic styling to perimeter-bolt SBC heads
  • Baffled design helps control oil splash and reduce blow-by
  • Fits Chevy SB V8 Gen I perimeter-bolt heads, 1958-1986, 262-400 CID
  • Perimeter-bolt only — won't fit 1987+ center-bolt Gen I SBC heads

Description

These finned aluminum valve covers are built for Chevrolet Small Block V8 Gen I engines with perimeter-bolt heads — spanning 262, 265, 267, 283, 302, 305, 307, 327, 350, and 400 CID — from 1958 to 1986. 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.

This is a perimeter-bolt mounting style cover — it does not fit 1987 and later center-bolt Gen I SBC heads, so verify your cylinder head bolt pattern and model year before ordering. At 2-9/16" external height, verify clearance with your rocker arm setup. 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.


Applications
Fits Chevrolet Small Block V8 Gen I perimeter-bolt head engines: 4.3L/262, 4.3L/265, 4.4L/267, 4.6L/283, 4.9L/302, 5.0L/305, 5.0L/307, 5.4L/327, 5.7L/350, and 6.6L/400 CID, 1958-1986. Common applications include Chevrolet Camaro, Nova, Chevelle, C10/C-K trucks, Corvette, Impala, and Monte Carlo.

Installation
Perimeter-bolt mounting style — does not fit 1987 and later center-bolt Gen I SBC heads (see TSP's Center-Bolt valve cover listings for those applications). Gasket, grommets, and mounting hardware are not included. Verify rocker arm clearance at 2-9/16" external height, and confirm your breather cap or PCV valve neck size matches the 1.25" breather/grommet hole.

Q&A

Will this fit my small block Chevy heads?
Only if they're perimeter-bolt style, used through 1986. This cover does not fit 1987 and later center-bolt Gen I SBC heads — see TSP's Center-Bolt valve cover listings for those applications.
