I have followed threads on Hemi rockers on here for some time now. There are a lot of guys that have said here that they have run the stock rockers for years with good success. And certainly, there are good reviews for T&D, DLI, Stage V and the like.

But there seems to be a lot of bad experiences for other brands of Hemi rockers. It almost seems that it is either best to run stockers, within reason, or go to the top ranks of rockers.

How do the newer MP stock replacements stack up? Are they up to the standards that their OE counterparts?

stock narrow or wide will do the trick with a cam lift under .750
at one time 9500 rpm was the norm for them

what about norris rockers?

Sometimes this forum can be a really big help, and money saver, thanks,was on the verge of buying some

The stock rockers work great but when you start checking ratios on each rocker you quickly find that they are all over the place. I sent mine to Tim Banning to be corrected, he called me and asked where I'd gotten them as they were really bad. He was nice enough to dig up a set of wide pad old pro stock rockers and rebuild them for me. Dave

So on a build where the stock rockers would be OK, how does a guy check the ratio ?

Thanks Dave.

I use to check one set of rocker arms at a time on one bank, make sure the lift at the lobes are all the same and like already said use checking springs I was terribly shocked on how bad the stock rockers vary on the ratio I saw right at .130 differences at the retainers in lift between rocker arms on the same cam

Cab you are so right. It can turn a normal guy into a tear streaked raving lunatic. Other than living with it the only options using stock rockers are to send them out for correction,(they can make them better but not perfect) or find a way to dig through and check dozens of individual rockers.
Mine were redone and I bought another complete set from a member here. I checked them all and used the best of them to make a set. Here are the ratios I ended up with;
on the intake 1.69, 1.63, 1.66, 1.66,1.67,1.66,1.65,1.63
the exhausts, 1.53,1.52,1.51,1.49,1.51,1.52,1.53,1.50
The net differences in lift on mine are only .026 on the intake and .017 on the exhaust, I can live with that. It still bothers me but it's much better than most.Dave

Where are we sending them these days? I know RAS had some problems lately. Tim Banning?

here. Jesel 8000-8200 rpm and no issues
