Cam and lifter problem

I've never heard the Rhodes lifters but the guy who owns the 454 says he had some in a 350 once and they sound allmost as bad as them. I talked to the owner and he's going to call Comp cams again and see what they say. Tomorrow I think we'll also try using the extension as a stethiscope to listen and see if it for sure sounds like all of them. From outstde it does.
Thanks for the input guys.
