The Edelbrock E-Street LS Cylinder Heads are premium quality, bolt-on-ready cylinder heads for any highperformance
or stock GM LS engine build. Sold in pairs and assembled with premium COMP Cams valve train
components, these LS heads are engineered with the same architecture as the factory head, and all stock
components will fit without issue. A Beehive valve spring option allows up to .570-lift camshafts while a dual spring
choice is good up to .660 of lift, ideal for many mild to hot camshaft grinds. A unique dual-spark-plug pocket design
allows you to use either a factory-style tapered seat or a gasketed seat spark plug, which are available in wider heat
ranges for maximum tunability.
