Cast Aluminum High Compression Ford Cylinder Heads

In the selection of a power head, do not be misled by high compression ratios. It is true, that if every power factor involved were 100% efficient, then the higher the compression ratio, the more power developed. However, where the engine is not custom made, it very often proves that a lower compression ratio will produce a higher overall efficiency. For special compression ratios, advise bore, stroke, and whether block is relieved.
