Are my lifters shot?

So yeah, am trying to diagnose some valvetrain noise issues, and had the car apart. Was wondering what everyone thought of my lifters, the bearing surface in particular. Basically on the bearing surface the shiny surface vs. the less shiny surface. All of my lifters have this to some extent or another. On the first picture the bearing on the left really shows what I'm talking about.

About 500 miles.

New FRPP.

Not planning on reusing the lifter with the oil hole drilled incorrectly either.

Were the lifter valley holes honed out? Or did you drop those in on a stock bottomend?

That does seem a little excessive, but some wear is going to happen.

Hopefully someone can help you out further...:nice:
 
lifter bores were not honed. Bottom end is all stock, basically installed new lifters with my new hci package about 500 miles ago. I'm just wondering If the bearing surfaces are supposed to shine up with break-in. Additionally you can still see the crosshatch pattern on all the lifter bores.

I did install the lifters without any oil or engine break-in lube on them. And cranked the motor over without prelubing the engine with the oil pump via the distributor shaft hole. I was wondering if that was my problem since they were run dry till oil got to them during initial warmup.
 
If you didn't prelube the top end, I'm betting they're shot. I coated mine in oil before I dropped them in, but I did prelube the engine since it sat on a stand for a year or so before I finally got around to finishing it up and installing it. Can you feel any of those grooves with your fingernail? If you can, I'd replace them or they may damage the lifter bore.
 
I can't feel any grooves with my fingernail. Just parts of the bearing surfaces are shined up really well. Is this something where I should replace them, or does this come due to normal wear?
