Description

Edelbrock Victor Jr. 23Â 220Âcylinder headsÂare an affordable option that delivers maximum power in high-performance street and entry-level competition engines. Its 64cc combustion chamber yields around 10:1 compression ratio in a typical flat-top application and about 12.5:1 when used with some of the most common 12cc dome pistons. One of the key features of the Victor Jr. 23Â 220 cylinder heads is the CNC machined chambers and bowls, which result in consistency and improved performance. They also feature angled spark plug holes and maintain the stock 23Â valve angle as well as the intake flange bolt pattern for use with 1986 and earlier intake manifolds. All of this allows these cylinder heads to deliver 530-580 hp potential right-out-of-the-box, making them ideal for a budget minded engine build desiring a high quality cylinder head that still uses a stud and guide plate rocker system. Bare heads will have valve guides and seats installed, but will require final sizing and a valve job to match the valves to be used. ** Combustion chamber volume:Â64cc; Intake runner volume:Â220cc; Exhaust runner volume:Â85cc; Intake valve diameter:Â2.10"; Intake valve diameter:Â2.10"; Exhaust valve diameter:Â1.60"; Valve stem diameter:Â5/16"; Valve guides:ÂManganese bronze; Deck thickness:Â11/16"; Valve spring diameter:Â1.55"; Valve spring maximum lift:Â0.700"; Rocker stud:Â7/16"; Guideplate:ÂHardended steel; Pushrod diameter:Â5/16"; Valve angle:Â23Â; Exhaust port location:ÂRaised .300"; Spark plug fitment:Â14mm x 3/4 reach, gasket seat. ** INSTALLATION NOTE: Check cam manufacturers specs for compatibility with valve springs for spring rates.

These heads require the use of a 14mm x 3/4in. reach, flat gasket spark plug with a heat range appropriate to your application.
