These cylinder heads are designed for maximum effort competition racing on 289 _ 351+ cubic inch based engines. The inline valve configuration features a 15Á valve angle and a modern combustion chamber design allows for high compression without large piston domes. The intake ports are raised .380"; however the intake flange has been extended to maintain proper port alignment with standard intake manifolds. The exhaust ports are patterned with a 2.50" spacing and raised .520" for high flow potential. These heads do require shaft mounted rockers; please contact Jessel and T&D for details. Two applications are available, semi-finished and fully CNC ported. The #77219 includes 47cc combustion chambers, ductile iron interlocking valve seats, bronze valve guides and requires professional preparation. The #612969 is a fully CNC ported version that features HIP processed casting for high density. The 60cc combustion chambers, 276cc intake ports and 95cc exhaust ports are fully CNC ported for maximum flow out of the box. Additional qualities include a 5/8" thick deck, 11/32" bore valve guides, and 1.935" valve centerlines. Edelbrock recommends 2.100" intake valves and 1.650" exhaust valves with 5.45" overall length.
