It’s a little known secret to those outside of the industry, but Edelbrock’s RPM Performer aluminum cylinder heads (PT# 60825, 60829, 60925, etc.) are consistently one of the best selling cylinder heads that Edelbrock offers. And these are the traditional 75-to-83cc, 210cc-runner RPM heads, not the “Max Wedge”-type Victors, either. When we first launched Mopar Connection Magazine 10 years ago, Edelbrock boasted that these were regularly within their Top 10 (if not often the Top 5) sellers.
That’s why it’s exciting to announce Edelbrock’s new Performer RPM 230cc cylinder heads. Available for hydraulic roller (PT# 60025), or flat tappet camshafts (PT# 60029), these new heads deliver top tier performance via larger 230cc intake ports and a fully-CNC’ed 73cc combustion chamber. Each of these heads are “machined to exacting tolerances in Edelbrock’s ISO-certified facility” per Edelbrock, and deliver top end performance comparable to more expensive competitor’s heads at a better price.
When asked how the new 230cc RPM’s compare to say, Trick Flow Specialties’ 240cc cylinder heads, Edelbrock told Mopar Connection Magazine, “Our RB head will come in as a step between our existing Performer RPM offering and the TFS Power Port 240. The peak flow will be a bit less than the TFS, which has their Street Port CNC program, where ours will be an as-cast port. Along with the new port designs, we have also improved the rocker shaft mounting bosses.”
Additional improvements over the 210cc RPMs include larger intake valves (2.19″ vs. 2.14″), greater valve spring maximum lift (.650″ vs. .600″), stainless steel swirl-polished valves with undercut stems (.3410″ vs. .3448″), bronze guides, ductile iron seats, Sure-Seat springs and smoother surfaces for better airflow and cooling. If improved performance without breaking the bank [$1344.95 (roller), $1367.95 (flat tappet)] is on your to-do list, Edelbrock’s new 230cc Performer RPM cylinder heads are right up your alley.
Here’s the original press release:
Edelbrock, a leader in high-performance automotive aftermarket components, is proud to announce the release of its new Performer RPM 230 cc Cylinder Heads, designed specifically for B & RB series Big-Block Chrysler engines. Engineered to deliver the next level of power and performance, these premium cylinder heads feature high-quality components and precision machining to meet the demands of serious street and strip enthusiasts.
Manufactured in Edelbrock’s ISO-certified facility in San Jacinto, California, each cylinder head is machined to exacting tolerances for exceptional quality and consistency. With larger 230 cc ports than comparable RPM heads and 73 cc fully CNC combustion chambers, this new design is ideal for high-performance applications that require increased airflow and power, while still maintaining compatibility with off-the-shelf components. These heads are intended for B and RB series Big Block Chrysler engines not required to meet emission standards.
Each Performer RPM 230 cc cylinder head comes fully assembled with premium valvetrain components, including stainless steel one-piece swirl-polished intake and exhaust valves with undercut stems for improved flow, manganese bronze valve guides, ductile iron valve seats, 2-ring positive oil control seals, hardened steel valve spring locators, and Edelbrock Sure-Seat valve springs, retainers, and keepers.
Edelbrock’s patented Clean-Cast Technology further enhances performance by eliminating internal casting flaws and creating a smoother surface finish, which improves airflow and coolant circulation. The result is increased power and better cooling right out of the box, making these heads an excellent performance value for any Big Block Chrysler build.
For application-specific use, Part #60025 is designed for Hydraulic Roller applications, while Part #60029 is ideal for Hydraulic Flat Tappet setups.
