    I was trying to figure out about a new concept of a head made for Harleys that are called Hemi heads. I think they came out or was in process of putting them on the market around 2010. What is the reliable workings of the head.Would it benefit a stock motor or a High performance motor. And all the necessary gasket, are they attainable. Are there weak points in the rocker arms.:newsmile058:

    Hemi heads have been around for years and there are several companies that offer them. This site answers most of your questions:

    IMO, Hemi head design is old tech, have a look at the construction of the combustion chamber on older models like the Shovel and Panheads, all using hemi type combustion chambers JMO
