The 400 Head Gasket with Steam Holes is a precision-engineered sealing component designed for small-block engines requiring reliable combustion chamber and coolant passage isolation. Built by FEL-PRO, a trusted name in OEM-quality gasket manufacturing, this head gasket serves as the critical barrier between your cylinder head and engine block. It is essential for restoring compression integrity and preventing costly coolant leaks into the combustion chamber.
The steam holes integrated into this gasket design allow controlled coolant circulation from the block to the head, preventing hot spots and maintaining optimal engine operating temperature during extended use or high-load conditions. This gasket features a multi-layer steel construction, which provides a consistent, durable seal under compression cycling and thermal stress—critical for engines subject to performance driving, towing, or sustained RPM operation.
This head gasket is ideal for mechanics and enthusiasts rebuilding 400-cubic-inch small-block engines, including Chevrolet 400 applications and compatible platforms requiring this exact bore and specifications. Its engineered thickness and precise bore sizing guarantee proper clamp load distribution across the head surface, minimizing the risk of blow-through or gasket failure that can compromise engine reliability.
