Efi-Diy

Here in Brasil we have a 12 port head in the 250. But the water passages are a little diferent than the old siamesed ones. In fact the 12 port head is worst than the old one. We also have a Stock car race category here, but instead v8 they used the 250 until 1999 with the siamesed head which works better then 12 port one.
I agree with Larry when he says that cut and weld is easier.
