OP has never seen a serious chev high horsepower stud girdle design. A band-aid to an initial and serious design flaw.
Chrysler rocker bar vs Chevy Ball stud design?

Adjust the valves lol
I use to crew on a blown Alcohol BBC Nostalgia car... Valve adjustments between rounds was. a PITA..
10-4. So back to the original question; yes, the stud design is junk compared to the rockershaft design. Case closed!

Ya mean Mopars don't need this mess?
This looks like "Penis Envy", like everything you can do to compensate for not having a rocker shaft lol.

Ok. I don't have a lot of experience with Chevy. But what I have seen with rocker failure, and what I have experienced in my own failures seemed to suggest that Ball Stud isolated damage better to that cylinder. This certainly doesn't suggest ball stud rockers would fail less. In fact, I'm agreeing with the reported observations on this thread.

I also agree on suspension. When Chrysler introduced torsion bars technology in '57. It was a quantum leap forward. In fact, I believe many monster trucks still utilize today. Both front and rear.
A few years ago I was watching one of those morning car show. Motor Trend or Car & Track. Can't remember what show. But the topic was Road course. They were exploring some of the complaints of mid 2000 cars lack of road performance. They tested the then newer Challenger. (pre Hellcat) The Camaro and the Mustang. (I believe they were all like 2005.) All 3 stumbled a bit on the road course. With the Camaro only edging out Dodge and Mustang by less then a second. At the end they brought out a stock base model '69 Charger 383. Just for fun and comparison. They were literally laughing expecting it to fall on its face. The test driver saying he has driven this era of car. After completing the course and running same time as the Camaro. The driver's first words was. "It handles better than you think it would. Yes, there is some body roll. But the 383 has enough power to pull you out of trouble. I of course was laughing at the TV. Lol. Knowing this was going to be the result.
The Dukes of Hazzard stunts were performed by '69 B-bodies. (I guess not always a Charger. But a Chrysler never the less.) Had that show been with an Impala ot Galaxy 500? Or even a Chevelle? Please.

This reminded me of something - I moved to sin city in 1994. My wife and I have/had many family members living in SoCal so we've made the 270 mile trip down the I15 probably a hundred times and I recall back between '95 & 2005 while travelling seeing quite a few vehicle fires or burned out hulks - every time it was a Chevy Truck!

Chrysler introduced torsion bars to Chrysler products, but not to the world. They'd been in use for quite some time; WWII tanks used it, the VW bug prototype had it, and Hudson was using it in the 1930s as did Citroen over in France. I do like the design.

You need to read the escapades of Rick Ehrenberg's "green brick" to really get the full picture. Mopar Action.

Stud mounted rockers are fine up to a point and then instability is the issue hence the girdles. The shaft mounted system is far superior but much less convenient. Most modern systems utilize the convenience of the independent mounted rockers along with the superior design of a shaft.
