In an effort to provide the best value and most American made crate engines, Tri Star will now be making the Dart SHP series cylinder head the standard head for our entry level small block Chevy engines.
Dart SHP heads are cast in the United States from A356-T6 aluminum alloy and offer upgrades superior to other aftermarket castings at comparable prices. These Dart castings are also available in a variety of intake runner sizes. The correct runner size allows us to better customize the engines to achieve the maximum torque at a low RPM for the best street/strip engines.
