Default Rocker upgrade

I had posted once about upgrading to 1.7 rollers on my LT4. All of the responses (thank you) were positive in this direction, and I think I want to go ahead with it. So my question is this, where can I find them? The only 1.7 rollers I've found are for either LSx or big block heads. I believe my stock springs will handle the extra lift, at least I am told. But what about the stud mounts? I know that the LT4 uses a special stud specific to this engine, so how do I go about making this change in terms of aquiring the proper parts? Any help would much appreciated if even a simple lead to the right direction. Thanks guys

I believe Nathan Plemmons did this one time. He may have used Scorpions but I'm not sure. I'm relatively sure though that Jesel, Harland Sharp or some other high level producer of serious valve train components could help you out. I've considered this someday too, down the road.

You'll have to change your rocker studs to run aftermarket rockers. Look for rockers that use 7/16" studs and guide plates.

As for the type of RR.... All of the above are top quality. Although I have found the best bang for the buck RR to be Scorpion... We are running them on our C3 383 w/ solid roller cam... all is well so far.
