Show original supplier description
The Manley Race Series exhaust valve kit is engineered for the demanding conditions of bracket, drag, and oval track racing, making it an ideal choice for engines operating under 8000 RPM. They feature chrome stems and hard tips to enhance longevity and wear resistance. The valves are swirl polished and fully machined, with polished under-head areas and machined combustion faces to optimize airflow and combustion efficiency. Available in Race Master (straight stem) and Race Flo shapes, these valves are particularly recommended for exhaust applications in alcohol engines. Key specifications include a 1.600-inch head diameter, 4.911-inch overall length, and a 0.3415-inch stem diameter. The valves also feature a 7-degree dish top of head and a Pro Flo underhead angle of 12.00 degrees.
