360 Magnum building on an existing bottom end

I finally cleaned up the pistons and removed the # 3 and # 8 rod cap to look at the bearings. Then removed the first and last crankshaft caps to look at the crank bearings. Also pulled the camshaft out to look at the cam bearings. This is what they looked like. The rod bearing may look like they could be replaced as it looks like there is some grooving. There for the crank may need to be polished. What do you all think? new bearings or use as is.
