Here is a pic of a Duggan older design head. It used shaft mount rockers and a canted valve arrangement. will see if i can also get some of a newer Deppe head. The cost of professionally designed and casting a New head is about 100K. And pic of a Sissell street head also a 12port with a straight valve arrangement
