5.9 stock Mopar Performance Magnum with EQ Hughs heads HP?

Thanks Bobzilla and 273....def leaning towards just a cam change and possible spring upgrade. Would love to keep all else as is....lifters, pushrods, rockers, no valve/head changes would make my financial day.
Research ongoing for best best cam selection.


If your leaving head stock you dont want to go to far over .500" lift., I think my cam is .513" on the lift which is basically the max.
