I done some reading on the tech info they have on the website.
Looks are very similar in design to the T/D's and jesels.
I'm gonna go out on a limb and say they are good, I know I wouldnt be afraid to run them on my 496.
Comp cams makes some good products, all their other rocker arms are very good, cant see these being any different.
On a side Note:
For what it's worth a friend of mine has ran their shaft mount rokers on his dodge 440, he was very pleased with the design and durability.
