"The oil dripping seems to be the valve covers, every time I go and tighten those fasteners up it either completely goes away or is drastically reduced. I have new gaskets and gasket-maker for them but I just can't bring myself to do that job with a potential intake manifold replacement in the near future, so I guess retightening periodically will be my go-to. I will try to get some lock washers, I applied some blue loctite on a few trouble fasteners but I think they get so covered in oil that it will make that useless."
I am with Jim...I run a tap down all these blind holes with brake cleaner and then blow out with air (cover anything important that might be exposed - like the valve train - and wear safety glasses). This works better when its on the bench rather than in the vehicle, but do what you got to do - holding a rag around the air nozzle and over the hole is how I would do it. Also, be careful not to overtighten the valve covers screws - one you warp the flange, it'll never stop leaking and they are hard to get ever get flat again....its common on an old engine that some previous owner has already dimpled them and thus they are leaking. On old iron blocks, I would strongly suggest use of cork gasket with a bit of gasket dressing or permatex #2....depending on how the heads were cast, some are reasonably flat on top, but old sbc's have a thin rounded top to the head, and a thin flexible cork gasket worked the best from my limited experience. I also like to use an 'extender' or force distributor that goes under the bolt head and on top of the valve cover the distributes the clamping force along a greater length of the cover flange - sort of like a long skinny washer....helps reduce the tendency of dimpling the cover flange right around the hole. I prefer to use use an external star lock washer instead of a split washer - not really sure why - but I think i like that you don't need much torque or compression for them to work, and that helps reduce the chance of over tightening.
oh - and when it finally stops leaking oil, you are probably a few quarts low and need to fill it
