    Spark plug location 5 hp B/S 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.

    Difference between 5.5 and 5hp flatheads

    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?

    Future of flatheads

    So what do you guys see in the future of flatheads. Think there are enough fans of the ole flatties to keep an aftermarket around or do you think they will die off soon? I really love the look and sound of a built flatty and would hate to see them go away.
