The Mini Cylinder Head calculation app implements the cylinder head calculations required when (re)building a classic Mini engine, to ensure that the correct compression ratio is achieved.
Many parts of the engine are mechanically interchangeable, but might require modification to get them to work.
Way back in 1998 we published a web page with these useful calculations, and this was very popular, although the original site is now gone.
So now the calculator is back! And better than before, but retaining all the original data/information that made it so useful.
