Description
Secure Seal Hardware. The Mr. Gasket Intake Manifold Bolt Set delivers dependable clamping and a clean, finished look for 1955-1991 Small Block V8 Chevrolet Corvette C1, C2, C3 and C4 models, helping your manifold seal properly for consistent performance. Purpose-built as a direct replacement, this matched hardware package provides the correct thread, length, and head style to simplify service while protecting gaskets from uneven load. It’s a small upgrade that pays dividends in reliability, leak prevention, and ease of maintenance.
Construction and Appearance. Each fastener is Grade 5 for balanced tensile strength and ductility, supporting stable torque retention across heat cycles without galling threads or snapping under routine service loads. The polished silver finish resists corrosion and wipes clean easily, giving the engine bay a tidy, professional appearance. Precisely formed 3/8-16x1 hex head bolts pair with matching washers to spread clamp load evenly along the rail, protecting gasket faces and reducing the chance of localized distortion. Tight manufacturing tolerances help maintain thread engagement and alignment for predictable, repeatable results.
Installation. This direct replacement set streamlines assembly: chase threads, clean mating surfaces, and position the manifold with the gasket dry or per sealant instructions as required. Start all bolts by hand to prevent cross-threading, then snug in a crisscross pattern from the center outward to seat the flange uniformly. Finish with a calibrated torque wrench in stages, and recheck torque after initial heat cycles for long-term stability. The included washers simplify achieving even clamp load and help protect finish on the manifold pads.
Application. This Mr. Gasket Intake Manifold Bolt Set fits 1955-1991 Small Block V8 Chevrolet Corvette C1, C2, C3 and C4 models. It enhances serviceability and sealing integrity by delivering correct-spec fasteners that distribute load evenly, resist corrosion, and keep your manifold secure for consistent vacuum, clean idle, and reliable performance.
