Fel-Pro intake manifold gasket set for Chevy small‑block V8 — 1204 kit, full repair seals for 262–400 engines

Fel-Pro 1204 is a complete intake manifold gasket set engineered to restore a reliable seal on Chevy small‑block V8 engines under demanding conditions.

This gasket kit supplies the seals and components you need when servicing intake manifolds on a wide range of Chevrolet small‑block engines, from early 260/262 variations through many 350 and 400 displacements. Fel‑Pro designs these parts specifically for repair environments, where block and manifold surfaces may not be perfectly machined, using proprietary materials and sealing features that help reduce leaks and simplify installation.

How does this gasket set deal with imperfect sealing surfaces?

The kit is built for real‑world repairs where mating surfaces can be warped, scratched or slightly uneven. Fel‑Pro uses engineered gasket materials and design elements that compress and conform to irregularities, improving the sealing contact and reducing the chance of vacuum or coolant leaks.

• Multi‑layer and composite materials that adapt to surface variations
• Profiled sealing beads to concentrate contact where needed
• Precision die‑cut parts to ensure consistent compression
