Description

The 440 Source Stealth Aluminum CNC Cylinder Head is a fully CNC machined cylinder head designed to improve engine performance. This head features enlarged intake ports, moving from the stock 212cc to 255cc, and exhaust ports designed for optimal flow. The precise CNC machining ensures identical and repeatable results for all ports.

This single head assembly is designed for use with a 3/4" reach spark plug, commonly found in small block and Hemi engines. Installation requires careful consideration of pushrod clearance, especially when using larger than factory diameter performance pushrods. It is recommended to perform a mockup to check for proper rocker geometry, pushrod length, and piston-to-valve clearance.
