BBC VEPR Roval Port Solid Roller Cylinder Head Package

Sharper cams. Higher RPM. Absolutely zero chill.

This is the package for builders who hear “valve lash” and smile. The 290cc VEPR Roval Port cylinder heads are built to breathe hard, rev clean, and keep pulling when lesser combos tap out. With 2.250" intake valves, 1.880" exhaust valves, 115cc chambers, and a 10-degree valvetrain, this setup is all about stability at RPM and airflow where it counts.

Fully assembled with stainless steel valves and 1.550" dual valve springs, these heads are purpose-built for solid roller abuse. No shortcuts, no “almost”—just race-ready hardware that wants to live north of 6,500 RPM.

The payoff?
With the right camshaft, this dyno-proven combo lays down 600–660 horsepower, depending on stroke, RPM ceiling, and how brave your right foot is feeling.

Proven Engine Combos (a.k.a. RPM With a Purpose)

Because spinning it to the moon only works if the parts can keep up:

• 3.766" stroke | 7,000 RPM max
  → High-revving, nasty, and efficient

• 4.000" stroke | 6,700 RPM max
  → Sweet spot of torque and top-end charge

• 4.250" stroke | 6,400 RPM max
  → Big-inch torque with serious pull upstairs

Bottom Line

If hydraulic rollers are “polite,” this package is loud, aggressive, and unapologetic. Built for racers, hard chargers, and anyone who believes horsepower should come with maintenance schedules and a little fear.

Spin it high. Tune it right. Let it eat.
