The center line between the cylinder bore and valves was increased with the 59 series blocks.

Kube, On the early engines The valves are located closer to the cylinder on the left bank than on the right bank. apparently the reason for different cylinder heads.
The difference is 2 1/2 degrees according to the engineering drawings.
If valve clearance wasn't a problem why would Ford make a different head for each side?
