Spent the money for the RAS and still had to buy some stageV's, there is a reason they are the best, also consider dechellies shafts, they had the nicest fit and finish that I have seen on any of them. Tim
Mine were better after the RAS blueprint, stock widepads but they were only 1.36-1.4 ratio at best, the stageVs are 1.51~1.52 consistently on the ones that I used. Tim

stage Vs. Or get a set of widepad stock rockers and send em to be rebuilt to rocker arm unlimited. they do great work and will blueprint ratios. stock non roller rockers work great. http://www.rockerarms.com/

If you read the Mancini add, the price listed does not include the shafts , springs or the stands, just the rockers and adjusters. So when you purchase the rest I bet you are close to Stage V cost. Just spend the money on stage V and be happy for the rest of your Hemi days
it's ok to butt heads, just don't do it with a butthead

Has anyone checked the accuracy of the DLI rockers? I have a set on one engine and have another set to go on the next project. They are certainly durable enough, but I had never thought to check their ratios until lately with all these posts.

You should really check every Hemiroid rocker ratio at the valves on any rocker arm your going to use   I use a set of checking springs and on one side of the motor and swap the rocker assemblys only, I set the lash at zero and carefully align the dial indictor stems to match the angles of the valve stems

[quote=SSDAcuda]Talking best?? When $ isn't in the equation… Ray Barton shaft rockers are the best!  Never ran the cam f/x but their lifters and customer service leaves a lot to be desired. And I ran Jesel's before and am a big supporter of ALL there products, and YES, RBRE rockers ARE THE BEST!! May cost a little more, but your buying them only once! [/quote Sorry to hear you had a bad experience with Cam Fx parts.......The rocker arms that Ray Barton sells for his hemi's are actually made by t&d.. And without a doubt there is absolutely nothing wrong with T&d rocker arms. I have been running t&D machine parts for years myself also. It is just nice to have a choice.and to see a new manufactur bring a really nice bulletproof piece to the market for our old Mopar's.....all cam fx rocker body's have a LIFETIME WARRANTY for breakage....

Maybe I should have payed closer attention to my stock rockers. Been there, done that....More than once, actually. Its usually not the rockers that cause that. Generally there was another cause. Too much rpm for the springs your running is the main reason we see, or lack of a rev limiter. Or what have seen more recently, the groove between the valve & the lock gets wiped out and drops a valve. Bad locks...But not usually the rockers fault.

It's mostly true that when you have a valve train issue it is usually caused by something other than a rocker arm.We found that the rockers for hemis offered on ebay and other site that are made in Canada or off shore to be junk.The rollers and pins are not hardened,the ratios are all over the place,adjusters are junk as is the thread pitch in the rocker.
If cost is no concern then The Jesel and T&D(Barton)and StageV are the best option.We have never had an issue with Indy rockers and run them on most all our hemis including Don's blower car,zero failures.The stock rockers are strong but need to be corrected for all out race application,for the street/strip they work fine.Landy,(if you can find them) have had pin issues and Norris(same) have pin and clearence issues,We have no experience with any other brands.Stay away for the Canada(ebay) junk.

They are most likely from off shore manufactures.We seen them eat up the rollers and pins is less than a few hundered miles.We seen the adjusters slip out of the threads and the stands not locate on the head bolt holes and alignment pins as well as the stand holes for the shafts be so far off when the stands are attached to the heads the shafts won't go through all the holes.
The warning should be quite easy to figure when they offer the complete assembly for around $1500 when most Mopar and Indy cost around $2000+ .Going cheap will end up costing a lot more in the end.The vender is in Canada but that doesn't mean they were manufactured there.

: That is one of the many reasons I call them 426 motors "Hemiroids" 
Maybe even there cast aluminum dual four intake if he decides to go with carbs. instead of EFI
