Can this head be saved?

Pictures will be posted at the bottom.

I'm going to drop by the machine shop this weekend, but wanted to know if I should just find a new head to take or if this one could be repaired and saved.

The pits are identical on the piston, cylinder 1/2/3 have these but #2 is the worst.

Had a miss shift, took it the engine apart after a compression test on #2 failed.
Cylinder 1- 149psi/ 2- 85psi/ 3- 151psi/ 4- 147psi.

Thats not enough pitting to worry about. Once the head is cleaned and surfaced most of it will be gone.

Did you find whet the engine ate to cause the pits?

If this head can be put back into service, yours can.

This is a common pitted head, that is rebuilt and bolted back on and run.

Now it looks like you have the factory installed 6T valves, thats a good thing! if you need a valve or 2 go back with the 6t valves, or go stainless steel, I just do not trust the cheap 2 piece shop replacement valves in a turbo app.

Thanks, we had 4 rockers come off and 1 shattered. That's the only thing we have found that could of caused this.

Something had to come thu the air inlet track, the roller followers coming off is something else.

How are parts of the follower going to make it from the top of the head into the combustion chamber?

Doubtful any debris made it thu the VC baffle and thu the PCV valve and into the IM.

Start at the air filter and go thu the whole inlet and turbo.

Pitting looks crazy but has to be easier to fix than dropped valve IMO.
