Speedmaster PCE281.2082.01 Chevy BBC 454 360cc 115cc Hydraulic Flat Assembled Cylinder Heads

The Speedmaster PCE281.2082.01 is a pair of pre-assembled cylinder heads designed for Chevy big-block (BBC) 454 engines. These heads feature 360cc intake and 115cc exhaust chamber volumes and are machined with hydraulic flat-tappet compatibility, making them suitable for street and performance applications that use traditional hydraulic roller or flat-tappet camshaft designs.

These cylinder heads arrive fully assembled and ready to install, eliminating the need for custom valve train setup or additional machine work. The hydraulic flat design is a proven, cost-effective solution for BBC 454 builds where reliability and straightforward installation are priorities. Ideal for hot rods, street engines, and performance rebuilds, these heads support a range of displacement and boost configurations typical of big-block Chevy platforms.
