The highvelocity intake and exhaust runners are CNC ported in the bowl area and the intake entries and exhaust exits are CNC profiled for increased air-flow. Combustion chambers are fully CNC machined for absolute consistency and combustion. High-quality conical beehive springs are secured with titanium retainers and valve locks for performance up to .600" valve lift. RPM Xtreme LT4 heads are equipped with guide plates and 8mm stem valves, adjustable (non self-aligning) rocker arms are required.

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.
