should i run this engine or not?

[SnS C10]

ok everyone so i posted a few threads about getting water mixed with my oil. also, looks to be like a spark plug hit my number 8 piston( i had bought brand new ac delcos and they did not hit). the plugs were put in from the previous owner. anyway, the engine was running perfectly fine, and i noticed an oil leak. it was milky. so i pulled the heads, and the gasket was blown. discovered the piston has little "dings all over it." Was going to pull the oil pan and check a few of the rod and main bearings to see what the bearings look like. if they all look good, is it okay to run the engine with the piston like this? since it seemed to be running fine to me, i dont see why not? engine is a stock 350 with hooker super comp headers, flowmaster, and petronix hei. I just need this truck to be able to move around and drive occasionally. I was thinking of just replace the head gaskets and bolting it all back together. the cylinder walls look okay as well. what do you guys think?
