I have some clone heads for sale. These are new everest 14cc head castings. They have been ported, and come in various valve sizes from 32x27, 32x25, and 28.5x25. They have all been flow tested and port velocity mapped. the data will be supplied with the particular head. They currently have no springs or retainers. You will need to specify your preference of spring pressure and alloy or Titanium retainers. They will come with lash caps Unless you do not need them. These heads fit the clone engines and hemi pradators. Non Hemi predators have larger head dowels and will need the two dowel holes enlarged. I can do that if you specify it.
