Guy, I need the advice of you more experoenced mechanic types...
I think I have two bad hyd lifters.
I keep getting a tick sound on the passenger side seemingly from the valvecover area.With a mechanics stethoscope, I have found two noisy lifters. With the stethscope probe on the poly lock, these two sound like someone striking a chisel with a hammer. The others sound like light tapping.
I have tightened both of these lifters, but nothing changes.
Are these lifters bad?
I better go check for header leaks too now that I think about it.....

Try backing them off until they get louder while running, then slowly snug them back up until they shut up. They may have bled down.
If they remain noisy then either they may need to be replaced or the cam is bad.------------------

I tried that on the two noisy lifters....
The rattle doesn't really change when the lifters are loose.....

Problem found!
The cam is wiped 
And I just sold a good solid lifter cam a few weeks ago.....
I wonder if the machine shop had my spring pressure too high?

A custom Isky Hyd. cam
The springs were set (supposidly) at 130# seat and around 330# open pressure. This was per Isky's instructions.....

Uh.....yeah! Sorry.  Kinda what I thought.
It's not too much spring pressure. That will not wipe out a cam, especially a girlyman cam.
Bad lifters, oiling problem, not enough break in lube, improper break in, any number of items can attribute to a cam going flat.
As I mentioned about a year ago, lifters, especially hydraulic ones are going to be a problem source.
Let me know if we can help you out.

Well, I had Eaton lifters, I have restricted oiling (restrictor drilled out to .125 for juice cam), and I think I used enough breakin lube. I get tons of oil on the top end judging from the oil on my fenderwells.
The lifter's plunger is frozen solid.....
Both lifters are on the passenger side.....
I think I followed the breakin procedure properly.
At this point, I really don't have a good answer as to what was the cause.

How much disassembly and cleaning should I do?
The engine actaully looks pretty clean inside.
I haven't pulled any bearings yet though.....
