Something to think about for the guys who want taller deck blocks. The way the cam and lifter bores are arranged on the new Hemi's would require a lifter angle change if the deck was taller. If the lifter angle was not changed you would have to clearance the heads for pushrods so much they would end up in the water jackets or ports. Head castings could be re-cored to have material in the pushrod tube areas. Changed lifter angle means different cam cores. Intake manifolds would be different. Just food for thought.
