Hi all, my name is Paul, I'm 23, and I'm new to the forum (obviously). I own a 1972 Datsun 510 sedan with a L20B and 5-speed conversion. The car has been parked for some 20 years +-3.
The car belonged to my father's cousin who sold it to my father after it was hit on the left fender. The damage was slathered over with bondo and the car repainted. :no: :no: :no: :no: and the car has been tinkered with only a little until the 20 or so years ago. Until recently, I have not done much to get her back on the road as it has played storage table and space-taker for many years because I was never into cars/car culture until about 7 years ago. It has become my project as my father has passed away.
Progress up until now involves primarily the removal and disassembly of the engine and head. The block awaits hot tanking and searching for cracks, the head cleaning, and the valves and valve train parts cleaned.
The big question I have at this time is this: the #4 cylinder on the block has some damage on the back lip which is approximately 1mm in height and depth (same size as the bevel of the lip), so it essentially can be removed with an overbore of 1mm which I think is unnecessary at this time as I simply want the car to be able to be driven in the "near" future.
Will this be a problem if I were to reassemble the engine without removing the damaged section? What would your recommendation be in regards to this, I have read up on a L20B being bored 2mm over and using a Z22 crank, rod and piston assembly but as stated before, I want to keep it simple at least for now.
Thanks ahead of time!

The damage is "visibile" (blurred by terrible focus on old phone) near the top. And that is surface in the passages from having drained the coolant a while ago.
