Product Details

The Speedmaster PCE251.1005 guide plates are engineered to prevent pushrod deflection under high-RPM conditions in Chevy small block 350 engines. These precision-made components ensure proper valvetrain geometry and consistent rocker arm operation, critical for performance applications.

Key Features:

  • Constructed from 5140 Chromoly steel for superior strength and durability
  • Nitrided surface treatment for exceptional wear resistance
  • Black oxide coating provides corrosion protection
  • 5/16" pushrod hole diameter for precise clearance
  • 7/16" stud hole diameter for proper rocker stud fitment
  • 2-piece adjustable design allows for individual rocker adjustment
  • Flat profile design suitable for standard valve covers

These guide plates are essential for high-performance builds, upgraded valve springs, or racing applications where maintaining pushrod alignment is critical to preventing premature wear and ensuring reliable valvetrain operation. The adjustable 2-piece configuration provides flexibility for fine-tuning individual valve adjustments while maintaining proper pushrod alignment throughout the RPM range.

Great

Wait time was a bit longer than expected but things happen.

Had received two deck chairs as a gift and were impressed with their quality and comfort. Decided to order 3 more. Can't have enough when gathering with friends and family.

Check mark.

Awesome price on a Yokohama tire for my Lotus. Delivered a day later than expected, but overall a good experience.

Received item as requested with fast delivery. Thank you.
