Bad Boy LT1 Heads

Edelbrock's new RPM Xtreme cylinder heads for GM LT1/LT4 engines (PN 61939) offer some of the best combination of as-cast port design and custom CNC-porting technologies available. By blending the affordability of as-cast ports with custom CNC porting in the critical areas (combustion chambers, intake entry, exhaust exit, and intake/exhaust bowls), Edelbrock engineers are able to improve airflow and overall performance. Additional features include LS1 valves and conical springs for improved airflow and high-rpm valvetrain stability. This proven combination yields a powerful cylinder head at a lower cost than typical fully CNC'd heads. They're available complete (PN 61939) or as a machined casting minus valves and springs (PN 61929).
