Edelbrock LT4 Performer RPM Cylinder Heads
For the ultimate performance, Xtreme heads are CNC ported for added hp and torque over standard Performer & Performer RPM models.
RPM Xtreme cylinder heads give you the best combination of as-cast port design and custom CNC technology 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) for improved air flow and overall performance. This proven combination provides you with a powerful cylinder head at a lower cost than a typical fully CNC'd cylinder head.
Edelbrock Xtreme heads are ideal for high-performance street and entry-level race applications. These heads are sold complete (unless noted) with high-quality springs, stainless steel valves and have heli-coil inserts installed in the exhaust flange and rocker stud bosses. Made In The USA.
