flatheads

Has anyone ever relocated the spark plug to a more centered location in the head? I have seen on other model B/S the plugs are in different locations in the head.

I picked this 5.5hp flat head today for $40..... its a good runner. I ran the numbers and it's a 1998, plain bearing block. Decal says cast iron sleeve. What is the difference between this and a normal 5hp? Is the bore and stroke the same? Camshaft? Carburetor difference perhaps?
