Edelbrock E‑Tec cylinder head for 302, 327, 350 and 400 SB Chevy engines with Vortec‑style manifolds features LT1‑style raised runner intake ports and a combustion chamber that positions the spark plug closer to center for more efficient combustion. It offers roughly 20% more exhaust flow than cast‑iron Vortec heads, strong performance up to about 6,000 rpm and can produce about 9.5:1 compression in a 350 with stock pistons. Dual‑drilled for multiple valve‑cover styles.
