I just looked on their site (Rocker Arms Unlimited); the only new rocker arms they’re offering for Mopar is "Chrysler Hemi 331-392 cid Adjustable Rocker Arms". There must be a huge market for these.

I had a set of Isky Ductile Iron rocker arms rebuilt by them probably three years ago. At that time, one of the original owners, Gary, was who I dealt with. He did mention that they’d talked about making the wedge based rocker arms again but, it does not appear that happened-maybe it’s still in the works. Give them a call.
