500ci rebuild steps...
You said the engine runs fine and does not use any oil so I would just run it. When I changed the heads on mine, my cylinders looked pretty much the same as that. The issue seems to be that the pistons in these combos have really short skirts which leads to piston rock (slap) and that's how the bores end up looking. The other question is what heads were on it? Those flat top pistons will result in a pretty high compression ratio with closed chamber heads. Mine are dished and are at about 9.5:1 with Edelbrock heads. (This picture is when it was first put together)
