This is a video of my 512 rb at idle 950 rpms or so. I switched to 1.6 ratio rockers over the winter and have not driven it much since. Cam card calls for .016 and .018 valve lash. I set it at .010 and .012 cold and have not checked it since. I know that the flat tappet cam will have some noise and my hot rodding neighbor says that it is normal. I can find no exhaust leaks and it increases with rpms.
What do you think? Anything to check when I double check the valve lash hot later on. It seems to run fine, but with over 500 ci, it is hard to tell.
