Many factors. Yes a head is more complicated. Time is also a factor. I think one bellhousing I did some design work cast $35K to cast prototypes. Due to time constrianst, it was needed in two weeks. Usual time is about a month. Also, were the part is cast. China is much cheaper, at least at the moment. So, we are comparing a price for a prototype to a limited production. Cost should be simular, but I'd think somewhat less for a production part.
Still, I was pointing out that the main cost would be the initial casting cope and drag or forms.
