I am going to use a 16V "Intergrale" head on my replica. It is possible to swap the cams 180 degrees. There is a guy in Spain who has done this modification on a Seat/Fiat RWD Rally car. If you look on the Guy Croft web site there is some information.
I will also make my own valve covers with Abarth cast into the top.
Cheers
Piers
