Replace these cam bearings? (Pics inside) Hey Everyone.
Trying to build up my LS1 for as cheap as i can.
The cam bearings in it have some score's and wear on them. the camera flash amplifys the damage, theres nothing sticking up, but i can catch a fingernail on the bearings.
The engine will see about 5-6k miles before it tear it apart again to rebuild it all with stronger components etc. So they dont need to last forever. It will see mostly low RPM cruising, but the occaisional track day. I was hoping to build the engine next week, so if i can get away with these i will, but on the otherside i dont want to **** my cam (TR230)
Opinions greatly appreciated:

Hey man, I think we were taking in the other thread of yours. Those are not bad at all. I had to put together an engine (in a hurry for a friend's daily driver) with cam bearings that had much, much deeper scratches and scoring on them. It's still running fine thousands of miles later.

I have read that the bearings are line bored at GM so replacing them may be higher risk. If that is smooth I would run it, if not hit it with a little 1000 grit and oil to smooth it out so there isn't a raised ridge.

I'm with vettenuts.
But, I would do it a little different. Start with the 1000, then move up to a 1500, and then finish with a 2000. Plenty of oil too. Use the oil to flush after a few passes to wash away any grit and keep it from scratching it any worse.
