Fel-Pro Exhaust Manifold Gasket Set for Big-Block GM V8s 1412 — Perforated Steel Core, High-Temp Fiber Facing

Fel-Pro 1412 is a performance-grade exhaust manifold gasket set engineered to seal high-temperature exhaust ports on big-block V8 engines reliably under racing and heavy-duty conditions.

Built for classic and performance engines, the Fel-Pro 1412 gasket set replaces fragile paper gaskets with a reinforced, multi-layer construction designed to resist blowout and burnout. This kit fits a range of big-block GM V8s and includes features that simplify installation and future service while maintaining a durable exhaust seal at elevated temperatures.

What makes this gasket set better than basic paper gaskets?

The Fel-Pro 1412 uses a perforated steel core with high-density fiber facing bonded to both sides, giving it much greater strength and thermal resistance than simple paper seals. The robust construction reduces the risk of exhaust leaks and deformation under extreme heat.

• Perforated steel core for structural integrity
• High-density fiber facing resists hot-gas erosion
• Designed to resist blowout and burnout in high-temperature use

How does it help with installation and later engine service?

Fel-Pro added practical design elements to make fitment and service easier. Slotted bolt holes provide flexibility during header alignment, and a nonstick surface reduces adhesion so the gasket can be removed without tearing when disassembling the exhaust system.

• Slotted bolt holes speed alignment and mounting of headers
• Nonstick coating prevents gasket from welding to flanges
• Easier removal lowers risk of flange damage at service

Which engines and applications does the 1412 fit?

This gasket set is intended for big-block GM passenger and performance engines. Confirm exact fitment using your vehicle details before purchase because not all variants and emission-controlled applications are supported.

• Compatible with GMP Performance V8s: 396 (6.5L), 402 (6.6L), 427 (7.0L), 454 (7.4L), 502 (8.2L)
• Not intended for emission-controlled vehicles—check fit notes
• Always verify year, make, model, engine, and trim for confirmed fit

Will this gasket hold up under racing or high-output conditions?

The layered steel-and-fiber design and thermal-resistant facing provide far greater durability than paper gaskets in high-heat environments. While built to withstand demanding use, select this part only for compatible engines and applications noted by the manufacturer.

• High-density facing helps resist hot-gas erosion and leaks
• Perforated steel core reduces chance of blowout at high pressures
• Engineered for performance and heavy-duty exhaust loads

Who is this for? The Fel-Pro 1412 exhaust manifold gasket set is aimed at restorers, hot-rodders, and performance builders working with GM big-block V8 platforms who need a reliable, serviceable exhaust seal. If you run a high-output or track-influenced engine and require something more robust than stock paper gaskets—but still need easy installation and future removal—this set is a strong choice. Always check the vehicle compatibility notes and fitment tool before ordering to ensure correct application.
