How bad is bad? (cam journals scored)

[Slow and Jerky]

I managed to do a real number on my cam journals. I have been checking the forums and several posts have suggested that Engine Dynamics in California can fix scored cam journals. But before I send my head down I am wondering if these are obviously too far gone...?

Bad news for me, Engine Dynamics said no go on my head. I have two questions: 1) Is it 06-09 that will work?

Oops, I really do have two questions, the other is am I correct in assuming that putting a used cam in a used head is a really bad idea?

I don't think you ever mentioned what year yours was, but the heads in that range are interchangeable.

It can be. The camshafts run very tight clearances, and a cam that was .0005" too tight could cause big problems all over again. Check the clearances as you assemble the head, with Plasti-Gage, the way the manual shows.

It's an 06; I am just wondering what (if anything) I can salvage from the old head. There are a couple of used heads on eBay at the moment with and without cams. The guys that are selling without cams seem to want as much as guys with......

I just ordered a used head (with cams) from eBay. When it comes in I plan to check the cam clearances, is there anything else other than obvious damage/wear that I should be looking for?

Also, is there a way to check the oil pressure? I am a little concerned about what killed the head in the first place. The oil pickup was not plugged and it appears that the oil passages were clear. My guess is that I torqued the caps wrong or maybe the cheap base gasket I used failed (no more aftermarket gaskets for me btw). My plan is to pull the valve cover and check for oil after I get it together (maybe turn the engine over without starting until I can see fresh oil ? Suggestions?

Hey Gray I have a question I feel doesn't warrant a new thread. The cylinder head off my 2007 wr450 has very similar damage. I need to get it fixed soon and have been in contact with Engine Dynamics. Problem is they are about a month out right now because of a sudden flood of work and some events coming up. Anyways I was wondering if you knew of anyone else capable of repairing these? Thanks Gray!

Millenium Technologies is another.

Tried them too. They're not set up to do journal repair. Dang, thank you though!
