This cathedral port head is engineered with the same architecture as the factory head, and all stock components will fit without issue. These assembled heads feature Beehive Valve Springs, chromemoly steel retainers, heavy-duty stainless steel valves, and top-quality valve seals – all inspected and assembled by qualified Edelbrock technicians.

The Beehive Springs are good up to .570” lift, ideal for many mild to hot camshaft grinds. Edelbrock E-Street LS Cathedral Port Cylinder Heads are manufactured with premium material and machined to the industry’s tightest tolerances.

All Edelbrock cylinder heads feature patented Clean Cast Technology, a revolutionary process that eliminates casting flaws and promotes a smoother internal surface finish for greater air and coolant flow. These benefits provide more power and increased cooling ability right out of the box.

A unique dual spark plug pocket design allows you to use both the factory style tapered seat spark plug or gasketed seat spark plugs that are available in wider heat ranges for maximum tunability.
