Other than that they seem to work fine. Actually thinking of swapping to their new Shaft mounted magnum rockers which weren't available when I went with the ones I have.

I've had mine for several years now with no problems running a fairly large hydraulic ( over .600" lift ). They are a pain to adjust though ( getting the roller tips centered on the valve stems ). I'd go with the new shaft set up too, but it's a little pricey at this time. Fastest 300

They are more of a conventional Chrysler setup and the problem with centering the roller over the valve stem should be eliminated. The current setup has about 1000 miles and 6 dyno runs on them and so far so good.
