Review TRW Chevy Pushrod Guide Plates Sbc Comp Cams L79 Aluminum Heads 202 fits SB

The **TRW 49008 SB Chevy Pushrod Plate Set** is a meticulously engineered, high-performance upgrade designed specifically for Chevrolet pushrod applications featuring **Comp Cams L79-style heads**, making it an ideal choice for enthusiasts seeking enhanced durability, improved valve train performance, and a refined bolt-on solution for their small-block Chevy engines. This premium pushrod plate set is crafted from **high-strength, heat-treated steel**, ensuring exceptional rigidity and resistance to warping or deformation under high RPM and aggressive camshaft profiles, which are common in high-revving, high-performance setups. The **SB designation** indicates a specialized design tailored for **small-block Chevy engines**, particularly those with **L79-style cylinder heads**, which feature a unique valve cover mounting pattern and deck height that require precise clearance and alignment. These pushrod plates are engineered to accommodate **Comp Cams aggressive camshaft profiles**, including their **L79-specific grinds**, while maintaining optimal valve spring retention and pushrod guidance. The **precision-machined surfaces** ensure smooth operation, reducing friction and minimizing wear on the pushrods, lifters, and valve springs, which is critical for longevity and reliability especially when paired with high-lift, long-duration cams. Additionally, the **integrated pushrod holes** are strategically positioned to optimize valve train dynamics, promoting better valve lift consistency and reducing the risk of pushrod binding or misalignment under heavy loads. Whether installed on a **high-performance street engine, a drag racing setup, or a competition engine**, this TRW pushrod plate set delivers the structural integrity and performance-focused design needed to handle the demands of modern camshaft technology without compromising on durability. For builders working on **L79 heads** whether restoring a classic Chevy or pushing a modern small-block to its limits this plate set serves as a crucial component in achieving a balanced, high-revving, and reliable valve train.

### **Pros and Cons of Buying TRW 49008 SB Chevy Pushrod Plates for Comp Cams L79 Heads (202 Series)**

1. **High-Quality Material** TRW is a well-respected brand in the aftermarket, known for durable, heat-treated steel plates that resist warping and wear over time. These plates are designed to handle high RPM and aggressive camshaft profiles without premature failure.

2. **Precision Engineering** The 202 series plates are machined to tight tolerances, ensuring proper valve spring seating and consistent valve lift. This reduces the risk of valve float or improper valve closure, which is critical for maintaining power and reliability.

3. **Compatibility with Comp Cams** These plates are specifically engineered to work with Comp Cams pushrod designs, including the L79 heads. The geometry is optimized to minimize binding and ensure smooth operation with Comp s camshafts, reducing the chance of valve train issues.

4. **Retention System** The SB (solid bolt) design provides a secure, non-slippage retention method, which is more reliable than some cheaper spring retainers. This is especially important for high-performance applications where valve train integrity is paramount.

5. **Warranty and Support** TRW offers warranties on their products, and their reputation in the performance community means you ll have access to technical support if issues arise. This adds confidence in the purchase.

6. **Durability for Forced Induction** If you plan to run forced induction (turbo or supercharger), these plates are built to handle the increased stress from higher valve spring pressures and loads, reducing the risk of failure under boost.

7. **Easy Installation** The design is straightforward, and they come with clear instructions. Many builders report that they install quickly without requiring extensive machining or modification to the heads.

8. **Proven Performance** Many high-performance Chevy builds (especially LS-based and small-block applications) rely on TRW plates for reliability. User feedback and forums often highlight their effectiveness in demanding scenarios.

1. **Cost** TRW plates are not cheap, especially when compared to generic or lower-end brands. For a set of four, the price can be significantly higher than budget alternatives, which may be a deterrent for casual or budget-conscious builders.

2. **Weight** While the steel construction is durable, it adds noticeable weight to the valve train. In high-RPM applications, this can contribute to slightly increased inertia, though the impact is usually minimal compared to the benefits of durability.

3. **Potential for Overkill** If you re running a mild camshaft or stock-style valve springs, these plates may offer more reliability than you actually need. For very low-stress applications, a cheaper option might suffice without sacrificing performance.

4. **Installation Requirements** While generally easy, improper installation (e.g., incorrect torque, misalignment, or cross-threading) can still cause issues. This requires attention to detail and may necessitate additional tools (like a torque wrench) to install correctly.

5. **Limited Customization** Unlike some aftermarket options, TRW plates come in standard configurations. If you need non-standard lift centers or unique geometry, you may need to source custom plates or modify the design.

6. **Potential for Over-Tightening** The solid bolt design can be prone to over-tightening if not careful, which may strip threads or damage the plate. This requires precise torque specification (usually around 15-20 ft-lbs, depending on the application).

7. **Compatibility with Non-Stock Components** While they work well with Comp Cams, if you mix in other brands components (e.g., different valve springs or retainers), you may need to verify compatibility to avoid interference or binding.

The **TRW 49008 SB Chevy Pushrod Plates** are an excellent choice for serious builders, especially those running **Comp Cams L79 heads with aggressive camshafts, forced induction, or high-RPM applications**. Their **durability, precision engineering, and compatibility** make them a top-tier option for reliability and performance. However, the **higher cost and potential overkill for mild setups** may not justify the investment for casual or low-stress builds.

For **stock or near-stock builds**, a more budget-friendly option (e.g., some aftermarket steel plates or even high-quality aluminum plates for lower-RPM applications) might be sufficient. But for **high-performance, forced induction, or reliability-critical applications**, TRW plates are a **strong recommendation** due to their proven track record and ability to handle extreme conditions without failure.

- You re running a **Comp Cams L79 setup with a high-lift camshaft** (especially 280 degrees or forced induction).

- You prioritize **long-term reliability and durability** over cost savings.

- You want **minimal risk of valve train failure** under stress.

- You re building a **high-performance or competition engine** where component integrity is critical.

- You re on a **tight budget** and the application is mild (e.g., stock or low-lift cam).

- You re running **extremely high RPMs with light valve springs** (where lighter plates might be preferable).

- You re unsure about installation precision and don t want to risk over-tightening.

For most **serious Chevy small-block builds with Comp Cams**, these plates are a **worthwhile investment** that pays off in reliability and performance.
