I have a set of these on my 440. The adjusters needed to be replaced due to one of them breaking on the dyno, used T&D adjusters in my case. So far they're holding up well. The ones I had for my small block had hardness issues on the rollers and were falling apart. They had CAT cast into them and these on the 440 do not. I still have no doubt they're made in the same place but apparently got the roller hardness figured out finally. Mine's running approximately .500" lift at the valve as well. I recommend name brand springs on those 'Source heads. Haven't heard much good about the chinese made springs and dropping a valve can make a boat anchor out of a good engine really quick. Maybe you already have good springs, didn't catch it if you posted that. Good luck, hope you don't give up on the project, good things take time.
Sweet! I will look into those for sure!
Thanks, Ricky
P.S.
Shame they don't make a clear valve cover set for your engine.

I wouldn't hesitate to run stock rockers on a .500 lift juice cam.
 Would probably be more reliable than cheap roller rockers. I've run stock rockers with a Comp 292 in a 440 for over 20 years with only one failure. Lots of street miles.

Thanks for the assuring words to my delima. I will tend to agree that several Roller Rockers setups would have very close to the same Pushrod lengths required for my assembly. When the poster said "he's got a set (of profom's) that are too short to fit any big block head and he's having to use them as paperweights" I breathed a sy of relief because I was worried that their was possibly an issue with the head geometry.  Thanks to you all! P.S. YOU TOO! I'm not deaf, just ignorant.

Ive run the Stealths on my built 440 since they came out.I did change the springs,retainers and keepers to Comps as my cam and engine are pretty radical for street.No problems at all with mine.I run an old set of Sig Erson adjustable iron rockers.That and Crane alloy 3/8 pushrods.With Eddys I would have done the same swap with the heads and then would have notched my domes to clear the angle plugs.Why they dont make a straight plug head is beyond me.Rocky

Changing brands of rocker arms may require a different length pushrod, too. When I was switching three different brands of rockers (Hughes, Indy/Dove, Harland Sharp) checking for the best geometry on a set of heads, none of them would have used the same length.
Do you recall and average measurement difference between them?
None within USABLE range?

Only saying... Since the relationship of shaft and shaft tower to valve tip shouldn't change. Considering the ratio of say 1.5. To maintain the 1.5 ratio, the relationship of the shaft to adjuster should be predetermined. Shouldn't that window of placement be the same or VERY close. If so, why would there be such variations in overall specs that would make them ( the pushrods ) unusable?

The arm itself might be a bit higher at the adjuster..
and to get all the companies to have the same specs
is highly unlikely

As noted by many here, these are all common problems with these heads, as far as pushrod clearancing goes. I think its crazy a 5/16 pushrod wont clear, but thats all part of the budget style heads. Is what it is. You save on the heads, but have to pay the shop to make the necessary changes. Happens all the time. The rocker issue is another story. This is exaclty why I had Harland Sharp change the length of their rockers when using them on Edelbrock heads. The roller tip/ valve centering wasnt right. With a Proform rocker, I harldy dount there was any engineering involved, they simply copied old Crane rockers and used the same dimensions I bet. The Cranes were great rockers for their time, but they too dont fit a Edelbrock or Stealth properly. The Harlands with the Edelbrock changes fit great, and so do the Hughes rockers. The Hughes are a great value for what you get, and the geometry is fine for these heads. All that being said, your builder already has pushrods that will hopefully work with something else. For the money, try and find some ductile Cranes or similar. Best bang for the buck for you. If you had some good stock rockers, or MP heavy dutys, they would work fine too, but then your right back into needing different pushrods. The Cranes would be a great compromise. Dont over engineer a very simple build here. Based on your budget comments, your not going to get a perfect fit of anything, but you can get something useable and still will live just fine...

Let me clear the air. I'm the one thats un-knowing. My engine builder is a well known professional with many years under his belt and his expertise and experience with especially big block Mopar would never be questioned. He was trying to save me a buck on this mild build and expected no big issues with the Proform parts. Lesson learned. I agree with some of you that we will resolve this issue by replacing the rockers with a better quality set. (I hope  ) I will post results as I receive them. Cant find the "Graemlin" for Crossing my fingers.

If this is the case then why are you here asking what to do and second guessing the knowledge of the trust you are placing in the builder ?
Look down for the crossing your fingers , it right next to one that is sometimes appropriate in these type threads ...  ...

First, I didn't realize I was yelling in the subject line. Rookie mistake. Please forgive me. Second, I was not questioning the builder just wanting to hear from others about their experiences with Stealths and Proform combo's and what I might expect to run into. Seems I am NOT the first nor the only one that has traveled down that combo road.  I should have inquired about it sooner and prepared to spend more $. I know I know....

I can tell you this; I have a new found level of RESPECT for you guys like MR P BODY and the like! I never knew your level of dedication and commitment to go FAST! I am blown away at the costs of good performance parts. You guys either out of your minds or wealthy or a little of both. Congrats to you all with so much AIR under the wheels! WOW!!! Ricky

Unfortunately, no. The locations of the pushrod adjusting screws were different enough for each rocker that none of the correctly sized pushrods for one brand of rocker would have worked with the others.

The Proforms are like short (and cheap) versions of Cranes from what I've seen, not exact copies. There's a picture or two in AndyF's book that shows the difference in fulcrum lengths pretty clearly.
Crane golds I've mocked up on Edelbrock bb heads had pretty good rocker-to-valve geometry, but I didn't take it the next step to see if they were likely to have pushrod clearance issues. IIRC, the 1.6s were more likely to have that problem than the 1.5s.
