- Chevrolet Performance L76/L92 Aluminum Cylinder Head
The Chevrolet Performance L76/L92 Aluminum Cylinder Head is designed to fit any LS family engine with a four inch or larger bore. The LS-Series family of engines has continued Chevrolet Performance's tradition of raising the power potential of the legendary small-block V-8. The great cylinder head airflow potential has been a key factor in the performance of these engines. This aluminum production style head is no exception with great out-of-box flow potential and is a true bolt-on replacement or performance upgrade!
