Build a Boosted LS3 with Edelbrock’s E-Street Cylinder Heads with Inconel Exhaust Valves

A GM LS3 running lots of boost or big hits of nitrous is fun. All that boost or gas will also raise exhaust temperature to the moon, which is bad news for the exhaust valves in your cylinder heads.

You won’t have that issue with Edelbrock’s E-Street Cylinder Heads with Inconel Exhaust Valves. The Inconel material can handle the elevated exhaust temperatures that result from high-boost levels or large quantities of nitrous that send stainless steel valves to the trash heap. The heads are also ideal for use in marine applications with water-cooled exhaust systems.

There’s even more to like about the E-Street heads, like:
• They’re engineered to work with all stock accessories
• A356 T-6 heat-treated aluminum castings
• Clean Cast Technology™ eliminates casting flaws for greater air and coolant flow
• 260cc intake runners
• 69cc combustion chambers with 2.165/1.590-inch intake and exhaust valves
• Three-angle valve job
• Dual spark plug pockets work with tapered- and gasket-seat spark plugs, providing more heat range options to aid tuning
• Single beehive valve springs rated for cams up to .570 inches of valve lift
• Fully assembled with manganese bronze valve guides, powder metal interlocking valve seats, stainless steel one-piece valves with hardened tips, valve locks, and steel retainers

Edelbrock’s E-Street Cylinder Heads with Inconel Exhaust Valves for GM LS3 are sold in pairs.
