Speedmaster Chevy SBC 350 205cc 64cc Straight Hydraulic Flat Assembled Cylinder Heads PCE281.2010

The Speedmaster PCE281.2010 is a fully assembled cylinder head designed for small-block Chevy (SBC) 350 engines. Featuring 205cc intake ports and 64cc combustion chambers, this head is engineered for hydraulic flat-tappet lifter engines, delivering consistent valve actuation and reliable performance in street and mild performance applications. The straight-port design and pre-assembled construction allow for quick installation without the need for additional machining or valve work.

These cylinder heads are purpose-built for engine builders and enthusiasts seeking a turnkey solution for SBC 350 engine builds. The 205cc port size balances airflow efficiency with velocity maintenance, making these heads suitable for stock-displacement and lightly modified engines. The 64cc chamber volume is optimized for compression ratio optimization in standard-bore applications. Hydraulic flat-tappet compatibility ensures smooth valve operation with standard cam profiles, while the assembled-ready format eliminates core sourcing and reduces build time.
