Dart Pro1 200 LT1 Aluminum Heads
The Dart 200cc Pro 1 LT1 head is a fine example of port velocity and maximum cfm. This head would be a solid choice for a larger cubic inch street engine with a good sized camshaft. The 1.437" double spring is good for a .625" lift roller cam providing 130lbs. of pressure on the seat and 335lbs. open. The 200cc intake ports flow 272cfm and fill the 58cc combustion chamber with maximum efficiency that delivers exceptional performance across the power band. The stainless steel valves are 2.02" and 1.6" and are backcut, sitting on a 5 angle valve seat. Sold in pairs.
