Dart’s new PRO1 LS 12° 285cc CNC Aluminum rectangle port cylinder head for GM LS7 Compatible small block V8 engines take performance to the next level. This full CNC ported cylinder head offers higher performance and more versatility than factory designs.

The 12-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 285cc cylinder head retains stock valve angles, stock valve locations and stock valve train mounting with dowel holes to make installation easy and durable. The intake valves measure 2.200-inch while the exhaust valves are listed as 1.625-inches each. The combustion chamber is 66cc. The final flow numbers out of the box will be available shortly on Dart’s website. These cylinder heads require a minimum bore size of 4.125-inches and each head features six-bolts.
