Slant 6 Aluminum Performance Head

I have really great, viable ideas for an Al-u-minimum head

I don't doubt you. You're not the only one—there have been great, viable ideas turned into great, buildable drawings and plans. What nobody has (or is likely ever to have) is the money and time and inclination and resources and facilities to turn any such drawings and plans into aluminum heads, let alone at a price anyone's actually going to pay.
