Throughout this site we use many technical terms, and given the breadth of readership our site enjoys, sometimes we are remiss and incorrectly assume everyone knows what we are referring to. For those that do not, here are some explanations of the technical terms use. |

On over-square engines where bore size permits adequate size of valves, this is a cheaper and simpler method of obtaining the high thermal efficiency of the hemispherical head.
