Hi all, Im new to this s community and this is my first post.
So, I got an 04 F150 that had a timing guide broke. While I was in process of replacing the timing guides, tensioners, chains etc.., When I took the camshafts out to inspect I noticed that there is a lot of scratches on the cam bearings. My question is should I start replacing the heads along with camshafts or should I use fine sandpaper to smooth it out and put a new camshafts in?
Ouch, what a groove! If it was me... I wouldn't replace them. Make sure they're clean, maybe clean that part of the camshaft, put it back in and keep the oil clean. It's not like the cam shaft is going to break.

What I was thinking, is to use very fine sandpaper to smooth it out and just keep it as is but replace the upper bearings and the camshafts and add Lucas on every oil change. also one of the rocker arm was failed (stock) on the driver side and did some damage to the cam.

Do not sand them...you will do more harm than good. If you plan on keeping the truck, save up to replace them, if not, just do what Martian said.
+1, also, make sure you put the caps on exactly as they came off, or this will get worse in a hurry.
Nevermind.
Looks to me like you need new camshafts as well. I would either get new heads and new cams, or you could get your heads line bored and get new cams that are sized to the new bore size, or stock cams with bearings to make up the difference in diameter. If it were me, I would look for a pick and pull with heads that still have the cams in them and swap out everything. How many miles on the rotating assembly?

Reason: changed my mind
There are no bearings so you cannot replace that in any way.
You noted replacing the top bearing, there is none so I am not sure what you are thinking there. If you are referring to the cap, no, you cannot just replace the cap as it needs to be align honed to ensure a match.
However, I think there is a company that makes bearings for those heads that can be added. This would save you from replacing the heads and instead have a machine shop make the needed changes to add the bearings.
The damage is ugly and will result in lower oil pressure. You can use it as is but with the work and money you are putting in it makes it a tough choice.
You can sand off anything protruding to keep further damage down but DO NOT sand into the surface at all. This would begin to open the clearance and most certainly cause a failure, potentially a catastrophic failure.

Dirttracker18,
Thanks for your reply, yes I meant the caps (the top pieces that holds the cams). I think I'll just keep it as is without sending anything and just replace the camshafts and hope for the best. I haven't taken the oil pan off yet I wonder if there is any damage on the crankshaft.
Should heads be replaced or repaired?
