Fel-Pro Engine Valve Cover Gasket Set 1628 — Molded PermaDry Silicone with Solid Steel Core for Small-Block V8s

This gasket set replaces worn or leaking valve cover seals on a range of small-block V8 engines, offering a combination of pliable silicone sealing and internal steel reinforcement for lasting performance. Built to tolerate high temperatures and repeated service, the PermaDry molded rubber formulation helps seal imperfect surfaces and resists oil soak, making it suitable for both street-driven and performance applications.

How does this gasket stop oil leaks on older V8 engines?

The molded silicone rubber conforms to the mating surfaces and fills small imperfections that cause seepage, while the solid steel core keeps the gasket stable under clamp load and heat cycles. This pairing reduces the chance of extrusion or collapse that typically produces leaks over time.

• Molded PermaDry silicone resists oil breakdown and temperature cycling.
• Solid steel internal core prevents deformation under torque.
• Stainless compression limiters protect the sealing bead at fastener points.
• Designed to accommodate on-again/off-again removal without losing shape.

Which engines and applications is part number 1628 compatible with?

Fel-Pro lists this set as compatible with a range of small-block GM-style V8 engines commonly used in performance and restoration builds. It fits high-port 18-degree heads and several displacement variations that share the same valve cover sealing pattern.

• Fits GMP Performance V8 families including 262, 263, 265, 267, 283, 302, 305, 307, 327, 350, 400 variations.
• Works with 18-degree high-port heads and similar valve-cover configurations.
• Appropriate for street, high-performance, and some racing engines where silicone resilience matters.
• Useful in restoration projects where original-style valve covers are retained.

What makes Fel-Pro's molded silicone and steel-core design different from ordinary gaskets?

Standard fiber or cork gaskets can compress, soak oil, and lose sealing ability; molded silicone combined with a steel core keeps its profile and sealing force across thermal cycles. The integrated stainless compression limiters protect the critical bead where bolts apply pressure, prolonging service life.

• PermaDry silicone resists swelling and degradation from engine oil.
• Steel core delivers dimensional strength and repeatable clamping geometry.
• Compression limiters reduce over-compression and bead blowout at fasteners.
• Engineered for easier installation and dependable re-sealing after removal.

How easy is installation and what should I check during replacement?

Installation is straightforward: remove the old gasket, clean the valve cover and head flange thoroughly, and seat the new molded gasket in the cover. Check torque specifications for your engine and inspect the sealing surfaces for warpage or damage before final assembly.

• Clean mating surfaces of oil, old gasket residue, and debris.
• Hand-seat the molded gasket to ensure proper alignment before bolting.
• Tighten fasteners in the correct sequence to the manufacturer's torque specs.
• Inspect bolt holes and cover rails for damage; replace compression limiters if worn.

Who is this for: The Fel-Pro DRiV Engine Valve Cover Gasket Set 1628 is aimed at mechanics, restoration enthusiasts, and performance owners working on small-block GM-style V8s who need a durable, serviceable gasket that resists oil and heat. If you rebuild engines, swap valve covers frequently, or want a reliable upgrade over original cork/fiber gaskets, this set delivers a robust sealing solution that stands up to repeat use.
