Any way you shake it, I did something really stupid: Buying Fly By Night, Inc. parts off EBay, or my ham-fisted wrenching. I put my motor together in 2004 but life happened, it went on the back-burner, and it has yet to fire. Just now trying to get back in the game. Recently, while reading threads about roller rockers, I decided I should go back in and check them/adjust them based on the info shared here in Moparts. Long story short, some of the adjusters sheared right off while LOOSENING them. I read in one of the threads that the locking nuts should be torqued to 25 lb-ft. Well, I hadn't applied even a fraction of that torque to the ones that sheared. Are the adjusters supposed to be that delicate? If not, can I buy just the adjusters from Harlan Sharp or somebody reputable? (I believe these rockers are knock-offs of H.S.) If I could go back and do it over again, I would pay the extra $$ for some steel roller rockers from comp cams or somebody. I knew better than buying cheap parts, but I just couldn't pass up this "good deal." And the set looks like they were put together right, but now I'm wondering if the roller tips are gonna come flying off if I rev it past idle. Please, I don't want to argue about whether I should even have roller rockers. I just need some advice in a bad way. First off, did this happen because of cheap Chi-Com metal, or could I have done something wrong during adjustment to cause this? Thanks, Moparts.

I won't argue with that. Sounds like I'm not the first to do this?

I did the same thing. Bought some Pro Form rockers and had a few of the adjusters break on me. I replaced the damaged rockers and swapped out the screws for MP ajusters and haven't had a problem since.

Yeah, mine are not H.S. knockoffs, it turns out, but ProForm. MP sells the adjusters independently?

Thanks, everybody. Andy, all I can find from Smith Bros online are pushrods. Nothing else. I'm not having luck finding the adjusters from MP either. How can I tell if a roller is going bad? This is really scaring me. Apparently the only American-made rocker arms out there are the Harland Sharp wallet-busters. And as if they weren't far enough beyond my budget, I'd have to get longer valves, too! Mamas, don't let your babies grow up to be gearheads...

Harland Sharp says you will--I guess because of altered geometry.
first time I ever heard that

We learn something new every day Johnahah. unless he is running a big cam with high pressure springs there is no need for rollers either. Could just as well go with a set of doctile or:
