Description

Blocking off unused exhaust ports on your Small Block Chevy prevents unwanted air leakage and ensures optimal exhaust scavenging, which is critical for maintaining consistent cylinder pressure and maximizing power output. These Allstar Performance plates offer a cost-effective, bolt-on solution to seal off ports on 23-degree heads without requiring machine work or complex fabrication. Whether you're running a naturally aspirated or forced induction setup, proper port blockoff is a fundamental tuning step that serious builders shouldn't overlook.

  • 1/4 inch thick plastic
  • Black finish
