I have a 135,000 mile full flow 289 from a 1964 Cruiser. The heads are leaking exhaust into the radiator water, so I know I need to take the heads off and possibly replace at least one head. The other portion of the issue is that now the oil pressure has dropped. It used to be at start up (cold) oil pressure was 65-70 lbs and after warm up/driving oil pressure would drop to 20-25 lbs. Last week while driving, I noticed after warm up the oil pressure had dropped to 5 pounds. After cooling down (next morning) the oil pressure only goes up to 45 lbs, then drops to 0-5 lbs after warm up.
My question is, after pulling the heads, I will do a complete redo on the heads (new values, harden seats, valve guides, etc), but how do I determine if I can do an overhaul or if I have to do an engine rebuild? I would prefer not to have to do a re-build. But I also don't want to make a mistake. Thoughts? Obviously I am no longer driving the car until this gets fixed.
Thanks in advance
