The problem with replacing the core plugs with the engine in situ is having enough room to swing the hammer to punch in the centres. Heavy hammer and a small socket, mind your fingers! Good luck with that. Clean and fully derust the holes in the block. A thin bead of Marine JB Weld is good where the plug seats especially if the block has some pitting.
