Brand New Edelbrock RPM Cylinder Head for 1958-1965 Chevrolet "W" Series 348 & 409 Engines with Hydraulic Flat Tappet Cam (Part #60819). 

The Edelbrock #60819 Performer RPM cylinder head is designed for 1958-1965 Chevrolet "W" Series 348/409 big-block applications. The Edelbrock #60819 Performer RPM head is perfect for street performance, daily drivers, street rods and muscle cars where seat-of-the-pants performance is needed. This cylinder head delivers great throttle response and power from 1500 to 6500 rpm. They also feature the highest quality intake and exhaust valves and valve springs.

Installation Notes:
  • Equipped with springs for use in hydraulic flat tappet camshaft applications
  • Original port locations and valve angles for bolt-on convenience
  • CNC port matched 220cc intake and 115cc exhaust ports for optimum flow and power
  • 1958 348 C.I.D. applications will require modifications to cylinder head (contact Edelbrock tech department for detailed information)
  • Use Edelbrock head gasket sets
  • May be used on 348 engines with valve lifts up to .550" only
  • Recommended spark plugs are Champion RC12YC or equivalent 14mm x 3/4" reach with flat gasket seat
  • These heads will only fit 1958-65 348 C.I.D. "W" engines if an Edelbrock #5409, #7159 or stock large port 409 C.I.D. manifold is used
  • Proper cylinder wall notching must be checked to ensure exhaust valve to cylinder clearance
  • These heads require custom length (8.65", 9") 3/8" diameter hardened pushrods. Use Edelbrock #9635 kit or equivalent. 
  • Bare heads will require the use of hardened guide plates; Edelbrock part #9609. 
  • Prior to installation, it is highly recommended that valve-to-piston clearances are checked and corrected to minimum specs, if necessary. A minimum of 0.100” clearance is recommended for both intake and exhaust.
  • If other than stock valve sizes are used, they may not work with the valve pockets in stock pistons, especially if a high lift cam is used. 
  • The use of aftermarket pistons and/or custom machining to your pistons may be required. Actual valve-to-piston clearance should be specified by your camshaft manufacturer.
