what would be the reason/need to replace the stock lifters with comps magnums? also is it worth the money to go withroller rockers? ive got a lq9 6.0 with a complete ls6 intake, headers, auto, comp 918 springs keepers and seals,317 heads (mild port and polish), about a 220/240/551 cam, stock rockers, arp rod bolts, katech oil pump. i'm not going drag racing just want a strong durable street/daily driver.i've read alot of cam threads and just wish that someone could translate whatever language they're in to plain english. thanx joel

 

With the lifts on your cam, Comp magnum would be overkill. Those are mainly for .600 and above.
Try Comp 850-16 or Crane ones

 

is it worth the money to go with roller rockers? depends on which ones you buy. the vinci/crane have been giving consistent gains as advertised.
