Please help with ticking noise

Yes, thread started in 2010 but still 2017 I got this issue.

Forgot to mention that after about 800 miles of driving the ticking is still there, the engine also have new stamped rockers.
The bottom is untouched.

Stamped rockers... So you have adjusted lifter pre-load by buying the correct length pushrods, I assume? If you can kind of locate the area its coming from, you might want to check the pre-load on the suspect rockers.
