Those lifters will be fine. Any update on the EQ heads? What are your plans on those?
I just pulled my magnum out to upgrade to a larger cam and edelbrock heads. It made 304hp & 342 ft lbs on a chassis dyno with a fresh out of the box and untuned demon 750, pump gas 91, and 104° weather. That was with 2.02 1.62 EQ heads and a 218/222 @.050, .539/.549 cam. Should have been 360-370 HP at the flywheel.
