The ticking noise from the lifters is higher pitched and not much of a concern. You can hear it if you listen by the valve covers. It goes away when the engine warms up.
Knocking noisies are deeper and more centered over the block and more easily heard at the back of the engine. My engine has always had a slight knock all the time, hot or cold and I have noticed it on other engines too. I am not concerned about it since I got a lot of miles on the engine.
I have been using Lucas Oil Additive with the Mobil 10W-30 oil for awhile now. It has really helped to decrease the start-up cold noises and has reduced the leaking from the valve covers.
GOOD STUFF
