The Chevrolet Performance Bare Vortec Small Port Bow-Tie Cylinder Head (19331471) is engineered to replace the 25534351 part. This cast-iron cylinder head offers 185cc intake ports and 65cc exhaust ports, designed for enhanced performance in small block Chevy engines. These heads are noted as some of the most powerful cast-iron options from Chevrolet Performance and are ideal for builds targeting 400-450 horsepower. They are designed to fit 1958 and later small block Chevy engines and can provide a 20 to 40 horsepower increase over earlier cast iron designs. As a bare cylinder head, this component is ready for customization with your preferred valvetrain components and assembly. It is sold individually.

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout.
