360 hydraulic lifter valve lash

Badsport said

What brand of cam? Were there springs recommended for the cam? I put a Comp cam (very similar in lift) in my engine and they recommended the 901-16 (I think) springs with damper. I have a slight tick with my Comp cam and after some research discovered that some of the Comp cams with their fast ramp drop allow the valves to close quicker giving a clicking sound. My car still does it, but have not noticed and problems as of yet.

Is it possible your springs don't have enough pressure?

i spent the good part of an hour on the phone and swapping emails with the techs before i bought this cam substantiating that my stock springs would support this cam. we felt confident that factory springs are good up to a .509 lift , though i have only used a .509 in a big block with 906 heads and factory springs and it ran great for a long time. at any rate, they were definitely interested in giving me info and not trying to sell me parts so i took this advice as good. it would seem to me that with engine off, having a hydraulic valve lash just shouldnt exist.
