Help with my first engine build (5.9 Magnum)

ValleyRat said
Cam bearings knocked out today and started cleaning valves.

Questions:

1. I noticed some scoring in the block after knocking out the cam bearings. Is this something to worry about? The rear most bearing hole (I don’t know the actual term) was the most scared up. It’s in the picture below.

2. When cleaning valves, is it okay to soak them in parts cleaner to help soften the carbon build up?

3. Can I use a brass wire brush on the valves, or is that too harsh for them?

I started cleaning them with wd40 and a scotch bright pad. But can’t get it completely clean with that method.

Sometimes if the cam bearing tool is tightened too much, the outer diameter of the tool arbor will be larger than cam bearing itself and score the journal like that. When knocking out the old ones, do not tighten the tool very much. You will see how this can happen when you go to knock the new bearings in. Especially the rear bearing, the tool will catch on the block.
The scoring will not cause problems if there is no raised edges. If there is raised edges, gently knock the edges down with a round file or sandpaper on something round. Don't cause more damage, just debur the scoring so it does not distort the new bearing.
