Pocket Port

The Perfect Upgrade for 800-1200whp Builds

If you’re making 800-1200whp, a full port isn’t just unnecessary—it can actually hurt performance by increasing port volume too much, reducing efficiency under the curve. That’s why we created the Pocket Port, a cost-effective solution that leaves the ports stock but reshapes and resizes the critical valve pocket areas to improve flow where it matters most.

Pocket Port R

Now, for those pushing the limits on a stock port we’ve taken it a step further with the Pocket Port R. In addition to our proven pocket porting, we use CNC precision machining to reshape the combustion chambers, eliminating hot spots that can cause detonation. This is especially beneficial for high-performance builds running pump gas, allowing for:

  • More timing, resulting in lower exhaust gas temperatures (EGTs).
  • Reduced knock sensitivity, increasing reliability.
  • Better combustion efficiency, making more power with less risk.
The Benefits:
  • More area under the curve and the ability to make power at lower, safer boost levels.
  • Optimized combustion chamber shaping (Pocket Port R) to reduce detonation and allow for more aggressive timing (on pump gas too!)
  • Increased efficiency, reliability, and overall performance.
Services Include:
  • CNC Pocket Porting – Disassembly, cleaning, and CNC precision porting to optimize flow.
  • CNC Combustion Chamber Reshaping (Pocket Port R) – Eliminates hot spots that cause detonation, improving efficiency and power on pump gas.
  • GSC Power Division Bronze Guide Installation – New bronze guides and seals for enhanced durability.
  • HG Precision Valve Job – Restores sealing and maximizes airflow for consistent performance.
  • Bench Lash to Cams – Lash calibrated to HeadGames Motorworks specifications for peak operation.
  • Milling – Provides a flawless surface finish for proper sealing.
  • Professional Assembly – Assembled with expert care for ultimate reliability and performance.

Not All Parts Are Created Equal—Here’s How We Pick the Best for Your Build!

Valve Upgrades

Why Aftermarket Valves Are Essential

At this power level, upgrading your OEM valves is a must! Aftermarket valves are built with high-strength materials designed to withstand the extreme heat and stress of high-performance applications. While aftermarket valves may bend under extreme conditions, OEM valves are more likely to break or burn—making aftermarket valves the safer, more reliable choice.

Is Bigger Better?
Not in this case! We don’t install oversized valves in the VR38 because they’re unnecessary. In fact, we’ve achieved 2000whp on stock-size valves.

Fun Fact: If your cam has less than 10mm lift, oversized valves can actually reduce performance because the oversized valve actually flows less air under 9mm of lift! Bigger isn’t always better—it’s about using the right components for maximum efficiency and power!

Spring Pressure Considerations

A common concern when selecting a spring kit is adding too much spring pressure, particularly for street applications. However, when it comes to spring pressure, more is generally better than less. Insufficient pressure can lead to valve float, which can cause significant damage to your engine. Proper spring pressure ensures stable valve control and prevents potential issues at higher RPMs.

Importance of Correct Valve Spring Pressure

The right amount of spring pressure ensures the springs remain controlled, which in turn keeps the valves functioning properly. The number one cause of valve-train or cam/bucket failure is using the wrong valve spring for your application. If the valve spring isn’t up to spec, nothing else in the system will perform at its best. Proper spring selection is key to maintaining reliability and preventing costly damage.

Choosing the Right Camshaft

Planning to relax in a lawn chair and listen to your car? If so, you might be tempted to go for the biggest cams on the market, and while it’ll certainly make your car sound great, it could also make it feel laggy. A camshaft that’s too large can deliver the sound you’re looking for but at the cost of drivability, especially in terms of throttle response and power delivery. Choose a cam that matches your performance goals for the best balance between sound and feel.

The Best Cam for Your Boosted Adventures

If you love pushing your car to its limits and diving into boost on the street, a smaller cam is the way to go! For up to 1100whp, we recommend sticking with GSC Power Division S2 cams, they are the perfect upgrade. We recommend GSC Power Division S3 cams for anything above 1600whp.

These cam choices deliver plenty of area under the power curve, ensuring smooth, reliable performance that keeps your car pulling hard and your smile wide for miles of boosted fun!
