Get More Power Out of Your GM LS with Edelbrock E-Street Cylinder Heads for LS1/LS6
Edelbrock E-Street Cylinder Heads are just the ticket for making gobs more power with your LS1/LS6-powered hot rod. These fully assembled, bolt-on ready heads are engineered with the same cathedral port architecture as factory heads so all the stock components will fit without issue. The E-Street heads are cast using Edelbrock’s Clean Cast Technology™ to eliminate casting flaws and promote smoother internal surface finishes for greater air and coolant flow. Other features include:
- A356 T-6 heat-treated aluminum castings
- Larger 210cc/75cc intake/exhaust ports move more air through the engine
- Modern 64cc combustion chamber design improves air/fuel charge ignition
- Dual spark plug pockets work with tapered- and gasket-seat spark plugs
- Heads with single valve springs are good for cams up to .570 inches of valve lift
- Heads with dual valve springs work with cams up to .660 inches of valve lift
- Fully assembled with manganese bronze valve guides, powder metal interlocking valve seats, and stainless steel one-piece valves with hardened tips, valve locks, and chromoly retainers
