Specs:
For the ultimate performance, Xtreme heads are CNC ported where it counts. Edelbrock 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. XT Heads are sold complete with high-quality springs, stainless steel valves and have heli-coil inserts installed in the exhaust flange and rocker stud bosses. Sold individually. Made in USA.
