Does any of it drag on your fingernail?
If it does, you need to replace it!

On the other side...
I would inspect the Torrington bearing that was in contact with this plate!
I would bet some of the needle bearings are scored?
I would recommend to replace that Torrington bearing too.
At the same time, inspect the other Torrington bearing too...
It's not supposed to look like that unless we're talking really high mileage, high power, and / or lack of oil lubrication?

It does look worse in the pic than it is. There is one spot where I can catch my nail. Unless it went to scrap, I do have another plate from an N/A engine I toredown, or I have a friend who has one. Replacing it won't be an issue.

For what it's worth and IIRC that is how the plate look on the original teardown and rebuild. The engine is a JDM but did not appear to be high power. It had factory turbo, factory fuel injectors. That wear is on the underside/engine side of the plate and I'll certainly look over the bearing. I need to replace the top/cover-side bearing as I damaged it during dissasembly. Atkins sells them as a pair. I was going to call Dan and ask him to sell me only one because all the parts have about 2k miles on them.

One thing I'm thinking of while ordering parts is doing some porting. I would like to do at least some exhaust porting and maybe get templates. I have some ruined housings and N/A irons I can practice on.
