Product Details

The Speedmaster PCE273.1024 intake valves are precision-engineered for Chevrolet Big Block 454 engines, featuring a 2.250-inch head diameter with +.100" oversize length and an 11/32-inch stem diameter. These performance intake valves are designed to optimize airflow and increase horsepower in high-performance and racing applications.

Key Features:

  • Manufactured from high-grade stainless steel alloy for superior heat resistance and corrosion protection
  • 2.250-inch valve head diameter provides increased flow area for improved volumetric efficiency
  • 11/32-inch (0.344-inch) stem diameter for optimal strength and valve guide compatibility
  • +.100-inch oversize length accommodates performance cylinder head machining and valve seat work
  • Hardened stem tips resist wear from rocker arm contact and extend valve train life
  • Swirl-polished finish reduces surface friction and promotes smoother airflow
  • Engineered valve face angles optimize combustion chamber sealing

These valves are ideal for engine builders performing performance upgrades, rebuilds, or custom valve jobs on Big Block Chevy 454 engines. The oversize length provides additional material for precision machining to achieve exact installed heights.

Service was very good as well as the product

Price was very reasonable. Original OEM product. Quick ship time. I was very pleased with Boatplicity and I will definitely purchase from them again.

The Monroe shocks are the only way to renew the factory suspension to your Z55 optioned vehicle. As good or better than the triple price and now unavailable factory shocks.

Quick shipment!
