The cylinder head is available from Speedway Motors and other leading specialty shops.

Vortec cylinder head

When looking for a new cylinder head for your small block Chevy, the Vortec is an excellent option. This head is designed to accept early style intake manifolds. Unlike the LT1/LT4 reverse-coolant flow engines, the Vortec fits 1955-present small block Chevy engines. You can find these heads from several sources. Their pricing ranges from around $600 to $650 in stock condition. Compared to other heads, they offer an excellent value for performance.

The Vortec cylinder head is a production casting and can be mildly ported to increase the flow. However, this method is expensive and can cause cracking. Chevy’s Vortec head is a heavy-duty production casting, making it a more reliable investment. These heads also feature taller intake ports, which make them harder to install into small block Chevys. It is therefore imperative to check the bolt pattern before making the purchase.

When choosing a Vortec cylinder head for your small block Chevy, you should consider the type of valve cover. Some heads have cathedral-style intake ports, while others do not. The casting of the LS1 cylinder head is 319-T7 aluminum. This type of head is also designed for perimeter bolt valve covers. It is recommended to shorten the valve covers with an adapter if you are planning on installing the Vortec head.

The Vortec cylinder head for small block Chevy gained 35 to 40 horsepower in the first year of production. By 2000, GM introduced these heads for trucks and vans. These heads have a higher-lift camshaft, which means they produce more power. The’ski jump’ on the intake port’s roof is designed to increase air velocity. It is also wider than the original GM cast iron “camel-hump’ heads.

Dart 127121 cylinder head

If you’re looking to replace your existing cylinder head, consider the Dart 127121 cylinder head for your small block Chevy. This cylinder head is made from A356-T6 aluminum and features a multi-angle intake seat, radiused exhaust seats, and manganese bronze valve guides. Its weight and size make it a great choice for beginners or enthusiasts looking to improve performance on their small block Chevy.

The cylinder head features 64cc combustion chamber, 210cc intake runner, and 75cc exhaust runner. It has hardened rocker studs, a forged aluminum cylinder block, and a Magense Bronze valve guide. Edelbrock offers two-piece heads with a 210cc intake port, and 62cc for the exhaust port. Those two sizes are larger than stock and improve engine efficiency. In addition, the hardened spring cups and Heli-Coil(tm) threaded inserts protect rocker studs from long-term wear.

Dart 127121 SHP cylinder heads are designed to work with most off-the-shelf parts. Made from aluminum, this head offers significant power gains while being incredibly affordable.
