Is this also true in the hemi world? In other words are their hemi rockers that are crap, and if so what should I look for? This would be for a street car with 500+ cubes and a 4 speed. Thanks!

I use 1030 or 1040, because it gets oil to the roller tips quicker. If you are using a flat tappet cam, stock Hemi rockers will be fine.

He sent me three different sets and I had to send them all back, and I had to pay the shipping cost! Some of the roller pins could be pushed out by hand! From there I bought the Indy roller rockers and they were junk too! The Indy's have terrible geometry...terrible machine work...and terrible oiling! They didn't even clean off the burrs left by the machining process! I lost a lot of money trying to save money on buying crap! I finally bought Stage V rollers from Tim Banning at For Hemis Only, and they are they best I ever seen, and the price is not bad. I spent the extra money on the Manton T/F rocker shafts, which are over-kill on my street engine, but the finish is phenomenal! The Stage V geometry is absolutely perfect which saves money down the road on guides and such. The oiling design is great! The machine work is gorgeous! The finish on the bushings is so beautiful that I could see the difference with by bare eyes! Forget Indy & ebay 1hemiman & Mopar performance! Call Tim now, because he only get a limited number of per year. Also beware if you pay with a credit card. My Mastercard charged me a $56.00 fee for some sort of usage Canadian bullsh#t! Trust me! Learn from my mistakes!!!

Oyvind Mopar mopar Joined: Jul 2009 Posts: 413 Norway (old world)	I also bought a set. Same issues. I did not dare to buy with roller tips, and went stock type. They were too short and ground with wrong starting point for the radius. If used as is, it would have worn out the guides/valvestems in a short time. I checked with X-referance to stock old Mopar rockers and found out that the brackets were not the problem, but the rockers needed welding/extending and regriding the tips. Also lacked all the hold down bolts when I got the set. Too late for me in Norway to challenge the feedback when I finally got them. I have used stock rockers sold on the bag with better results, although some have had worn tips (easy fix). My old rockers ran 9000 rpms with Crane R290 in the old days, no issues with them. But I needed to check/grind the radius for correct fitness to the valvestem top with that camshaft back then.

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? Master, again and still

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

You have to mock it up with light checker springs. Install the cam and one intake and exhaust lifter, checker springs on said cylinder. Set the it at zero lash and using a dial indicator record maximum lifts go back to your cam card or using a dial indicator measure total lobe lift at the cam. Divide the maximum valve lift by the maximum lobe lift the product is your rocker ratio. You'll have to do this for each rocker arm. Dave

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
