Low Dollar RV 440 into a '79 Dodge Magnum

Unbelievably clean 440 .... all except one cylinder. I didn't do my usual and close the valve and lubricate the cylinders before storing. What a stupe I can be sometimes :( Does indeed have 452 heads. We checked oil pressure as well. Heads is where the time/work will be. Other than that, it will just be assembly and hope the one cylinder cleans up nicely.
