Product Details

The Manley 11504-6 Severe Duty Pro Flo Intake Valve Kit is engineered specifically for Buick V6 Stage 1 applications, delivering performance and durability for bracket racing, oval track, or high-performance street engines. This 6-piece valve set features a 1.775-inch head diameter designed to optimize airflow and power output in production cast iron heads.

Key Features:

  • Severe Duty series construction with NK-842 stainless steel material for superior strength and longevity
  • Pro Flo design reduces stem diameter in the fillet area for increased airflow and reduced valve weight
  • Chrome stems and hardened valve tips for enhanced wear resistance
  • Swirl polished and fully machined for precision fitment
  • 11/32-inch (0.3415-inch) stem diameter with stock installed height
  • 4.730-inch overall length for proper valve geometry

Manley's Severe Duty valves have proven their reliability through rigorous fatigue testing, enduring up to 100 million cycles at high stress levels. These valves are specifically engineered for Buick V6 3.8L Turbo Stage 1 engines and deliver the performance demanded by serious enthusiasts and racers.

Super fast shipping, exactly as ordered, no drama, problems or complications

Although there was a mix up with the shipping on my order customer service was helpful and expedited the solution and made it worth my trouble. I will be keeping Autoplicity in mind for any other parts I might need for my Jeep.
