Product Details

The Edelbrock 60735 Performer RPM aluminum cylinder head is engineered for 1955-86 Small-Block Chevy applications, including 302, 327, 350, and 400 cubic inch engines. This fully assembled head is ideal for street performance builds, daily drivers, street rods, and muscle cars where reliable power and throttle response are essential.

Key Specifications:

  • 70cc combustion chamber volume
  • 195cc intake runner volume for excellent airflow
  • 65cc exhaust runner volume
  • 2.02" intake valves and 1.60" exhaust valves included
  • Straight spark plug configuration for header clearance
  • Maximum valve lift: 0.575"
  • 1.46" diameter valve springs with 0.600" maximum lift capacity
  • Compatible with hydraulic roller camshafts

Premium Construction Features:

  • Cast from A356 aluminum and manufactured in the USA
  • Threaded inserts in rocker studs and exhaust manifold bolt holes for superior strength
  • Hardened valve seats and manganese bronze valve guides
  • Fully machined valve cover rails for consistent gasket sealing
  • 3/8" rocker studs with hardened steel guide plates
  • 9/16" deck thickness for durability

This cylinder head delivers excellent throttle response and power from 1,500 to 6,500 RPM, making it perfect for street performance applications. The straight spark plug design provides clearance for most aftermarket headers. Sold individually, completely assembled and ready to install.

Important Installation Notes: Requires pushrods 0.100" longer than stock when using factory rockers (Edelbrock #9629 recommended). Champion RC12YC spark plugs or equivalent 14mm x 3/4" reach with flat gasket seat are recommended. Not compatible with engines having less than 4" bore unless using camshafts with less than 0.450" valve lift. For use on pre-pollution controlled vehicles only.
