Ticking noise, 383, can't locate the source

I agree 100%, new doesn't = good, although it's sometimes easy to overlook.

Someone mentioned a cracked header, I'll check them again, and pull them if needed.

I'll check the springs closely.

Any recommendations for replacement rockers?

Also, I'm looking at all the pics I took so I can obsess over this when I should be working, does this retainer look off, as in not right?

I know pics aren't as good as being there, but I'm stuck at work.

I think I may see the problem. Can you get a better straight on shot looking directly DOWN at the valve tip? It looks like your sweep is falling off the edge of the stem.
