This is HKS camshaft 264/264, bought on ebay, still on the motor during the sale ( bad vendor )...

Well, i need to know if a polish is good before installation in my head ?

Thanks for your help.

They're certainly useable as is (concerning scoring on the cams, it appears to be normal wear from just running), although there looks to be a small chunk missing in the 1st picture on one of the lobes.

It's really hard to tell if there's any spots that are "dug in" from the pictures. I would at the minimum clean them up very well, put some engine assembly lube on the caps/moving surface when set it. If there is any noticeable scoring that will catch your fingernail with ease, definitely get them checked out.

If you clic twice on the pic and again on the imageshack web site, you have a nice vue from the spots !

And yes these spots are dug in.
I have found 25.86 mm in the dug for the exhaust cam journal.
Service limit is 25.95 - 25.97 mm.

I could sense this dug with my fingernail

Where is the small chunk on the first picture ???

Thanks.
