2009 600 etec decided to eat a wrist pin bearing. Root cause was I didn't install the wire retainer properly when doing the complete engine rebuild. Lesson learned Anyways I have located all pieces of the cage and accounted for all of the needle bearings. My question is the head got beat up. Im trying to find a good used one but is there any saving this one?

I would get a 2009 used head then pull it totally apart (engine) and check the damage. get a machinist to measure and check the new used head to the engine cases and new pistons and cylinders if needed. I would not try to save the head for numerous reasons.

Just smooth it up a little bit and use it...

That head is trashed.

I was guessing its junk but wast sure if it could be polished up and used. Im gonna look for a used one. Thanks. I love this site.

technically yes it can be used. the sled will run again on the head if you do some smoothing and rework on it. but the big question is why you would. eBay probably has them. the sled will run way better on a non-dented dome at 8000 rpm with less detonation risk. ect ect i would want to know where else all those cageless bearings went.

It was a caged bearing. I found all the needles still in the rod end. I pieced together the cage and found 1 small missing piece. That missing piece was found stuck in the top of the piston. Im 99.99% sure the lower end is good. Before I reassemble the top I will definetly try to blow out the crank case and maybe use a small magnet to look for any debris in there.

Just have a machinist check the used head for flat to the cylinders. Also have them check the new piston to wall make sure you get what you need or it blows from up too tight. Probably run one of the thicker base gaskets also.

I will take the head to work and Chek it for flatness. When I did the motor last I checked the piston to wall clearance and ring gap. Also check the squish or quench as my kit came with 3 different gaskets. Ill doo the same this time but also make sure I have the wrist pin circlip In correctly this go around 🤬

Was clip with the eye like a stock one? I find those difficult to install wrong, but I guess it is possible. Could it have anything to do the previous hesitation?
