    Chevy RPM Xtreme Cylinder Heads

    Designed for 1996 LT4 (or) 1992-97 LT1 small-block Chevy engines, RPM Xtreme LT4 cylinder heads are CNC ported in critical areas for improved airflow and peak performance. Features include high-quality 8mm stem stainless steel intake and exhaust valves that feed the high flow intake and exhaust ports. 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. Match with RPM Air-Gap intake 350-7109, throttle body 350-5210 and camshaft 350-2108 for the Total Power Package combo.

    Specs:

  • Deck Thickness: 5/8"
  • Rocker Stud Diameter: 3/8"
  • Recommended Pushrod Diameter: 5/16"
  • Maximum Valve Lift: .600"

    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.
