Available with 170cc or 200cc intake runners, these cylinder heads are assembled with one-piece stainless steel valves, 1.46 in. valve springs, retainers, and locks. The E-Tec models accept either centerbolt or standard valve covers, and work with most exhaust manifolds and headers. Match your vehicle specs to the correct Edelbrock head for precise fitment.
