At Superior Cylinder Heads, we highly recommend upgrading to new stainless steel valves when rebuilding LS and HEMI cylinder heads.
Many factory valves have already seen years of heat cycles, wear, and carbon buildup. Replacing them during the rebuild process helps improve reliability and gives you a stronger foundation for your engine.
Benefits of upgrading to new stainless steel valves:
• Improved durability and heat resistance
• Better sealing and valve-to-seat contact
• Reduced risk of valve failure from worn factory valves
• Great for daily drivers, towing, and performance applications
• Cleaner, more consistent rebuild overall
Whether it’s a stock rebuild or a performance setup, new valves are one of the best upgrades you can make while the heads are apart.
Our rebuilding process includes:
• Complete disassembly & inspection
• Hot tank cleaning & pressure testing
• Precision valve job
• Resurfacing to proper finish
• New valve stem seals
• Vacuum tested for proper sealing & compression
Available for many:
• GM LS applications
• 5.7 / 6.1 / 6.4 HEMI applications
