The Edelbrock E-CNC LS3 cylinder head is a fully CNC-ported replacement head developed for street and light-duty racing LS engines. It improves intake, combustion and exhaust airflow over stock LS3 ports and provides extra casting material for porters to work with while remaining compatible with stock-style rocker arms. Suited to cathedral-port or 3.89" bore LS applications, it balances street drivability with upgradeable flow.
