2,281.95

This fully CNC ported, 23 degree valve angle cylinder head is for the discriminating racer who wants the ultimate in performance and reliability. These cylinder heads retain the use of conventional intake manifolds and feature an evolved head architecture made to utilize the improved capability of the latest designed manifolds. Improvements over previous manifold designs include revised intake and exhaust valve locations, improved spark plug placement, and a new water jacket that is more head porter friendly than previous models. Manufactured with Hot Isostatic Press processing in which raw aluminum castings are heated to 900 degrees F in a pressurized chamber up to 30,000 PSI. This eliminated imperfections by removing any trapped gases or internal porosity. The result is an incredibly strong,dense sand casting that has three times the fatigue life and nearly the consistency of billet aluminum. The DR23 uses a stock Chevy head bolt pattern but requires a shaft rocker system and is designed to be used with Edelbrock 7-bolt valve covers sold separately under part number #EDE4259. Valve sizing is 2.40” on the intake and 1.88” on the exhaust with 119cc chamber volume. Port volumes are 377cc intake and 128cc exhaust. Sold each. Made in USA.
