What is "flatheads forever"?
What's with this "Flatheads Forever" stuff??? Several customers have inquired about this, asking if I'm a Ford flathead fan. Well, yes, but regarding the subject matter on this website, I'm referring more to the Kohler K-series engines which are of the flathead (or in more technically appropriate terms, L-head) design. Such a configuration can not be considered state-of-the-art in today's emissions-regulated environment, but it does offer advantages in simplicity and compactness when compared to the more modern overhead valve designs. The flathead suffers a bit from restricted breathing too, resulting in potentially less power output than the overhead valve counterpart. However, this can be largely compensated for by typical, well proven hot rod modifications (see links to articles that appear on this site). The Kohler K-series flatheads are very well-designed and rugged engines and will run many thousands of hours if proper maintenance is performed. They offer high reliability and dependability in service, and are truly "classics" that have stood the test of time - just like the Ford flathead. These are the reasons for my "Flatheads Forever" enthusiasm. This website and the products herein are dedicated to keeping these engines running at their inherent performance and reliability peak.
