worn out shocks vs. calvert 90/10's

hey guys,

just wondering if there would be a noticable benefit from switching from worn out stock 6cyl gas shocks in the front to a 90/10 shock, specifically the calvert as i have heard pretty good stuff about them. Would a worn out shock act similary in that it allows the front to rise and drop quick, or would there be a different with the 90/10 (even if its minute like in 60ft times or something)..what do you guys think?
