Has anyone in here used the pierce manifold msx cross flow head complete from the states?
Are they any good?

Casting cylinder heads is pretty low tech these days with the advent of 5 axis mills!!

I get considerably more flow through a 5 port B series than through the crossflow - the design is crap with too many changes of direction.
