I agree - plenty of life left in it. Alloy deck probably saved it.
I would personally squirt some oil into the inlet manifold with the spark plug facing up, allowing some onto the bore and to run down into the main bearings. Ideally you would also tilt a bit more to allow into top main bearings. Smokes for a few mins but worth it.
Thats effectively what I did with my survivor 1972 Victa Sunbeam
