No the amount of air that can be flowed basically. Water jackets get in the way of how the ports can be machined as well as size

So I guess the street heads will flow a bit less...

Most likely unless that do cathedral ports but that would require a new design intake manifold as well.

Do you need lube before or after the phone call.

They look very nice and from someone coming from a machine background. Those heads have some machine time on a 5-axis mill.
