  Dart's LS-based PRO1 LS 15-Degree 280cc Aluminum rectangle port cylinder head (LS3 compatible) for GM LS series small block V8 engines take performance to the next level. Offers higher performance and more versatility than factory designs. The 15-degree-based high-performance cylinder head has better airflow, more efficient combustion chambers, and more user-friendly features than production LS castings. The Dart PRO1 280cc cylinder head retains stock valve angles, stock valve locations, and stock accessory mounting holes to make installation easy. Virtually everything else has been improved.
