edit: added 3rd and 4th logical men, I see it this way, we can spend a fortune on an average oval port or invest in putting on head that has more potential and parts once fitted available off the shelf than any A series ever has.
Just perving at Kia engine bays today saw some other interesting options with ignition ecu, rocker covers and inlet manifold

just in case someone has missed it these are avail for the head
You wanna go quads I hear and for the price of a weber manifold for the A series you can go billet manifold for this head! to take 4age 20v quad itbs

only 300usd for billet unit much cheaper than cast A series weber manifold

This is the thread I discussed some other options, look at the pics

There are like 3-4 rocker covers available all interchangeable for the B series and the Z series head also with very narrow valve angle design
