[DeTomaso] Weber's or IR Stack EFI for high HP applications

Question --

Why are the IR manifolds being discussed made for the 2V heads?

Why is the generally better performing 4V head not the standard for IR manifolds.

I know just enough about engines to get me in trouble.

Hoping one of you engine gurus can explain this for me.
