The 351C/400 had oil supply/valve guide problems problems @ intro.
Did it do this before the cam upgrade? I would contact COMP CAM TECH LINE first and research CLV engine oiling mods in the meantime..

The oiling mods aren't really needed unless you spin high revs.

Did you check lifter preload ? Aftermarket cams can be ground on a different base circle than the old stock cam so you should check push rod length as well. Milling heads and block will effect push rod length and preload too.

I would pull that valve cover and locate the noise source then check the preload on that lifter. if it's loose, it could be a cam lobe going bad..
