IAG 750 CNC Pocket Ported Competition Cylinder Heads Package for 02-14 WRX, 04-21 STI, 05-09 LGT, 04-13 FXT

This is the point where the EJ head package starts making sense for real boost and track abuse. The pocket port work and upgraded valvetrain give you more room to lean on the combo.

• Port work: CNC pocket ported for better airflow without jumping all the way to the more aggressive race head packages
• Valvetrain: Built for higher rpm stability and harder use than a basic street setup
• Best fit: Strong choice for serious street, drag, or track builds in the mid-power range

Fitment: 2002-14 WRX, 2004-21 STI, 2005-09 Legacy GT, 2004-13 Forester XT

Why you'd choose it: Choose this when the short block and turbo are beyond a basic street combo and you want a head package that will not be the weak link.
