It would be better (and easier) to find a 1.2 carb or 1.3SR head and inlet manifold as they are more readily available and the 1.2 carb and 1.3SR heads are less restrictiven (and share the same cathedral port shape).

IIRC the 1.2SPI has square ports similar to to the 1.4SR (so look for a 1.4SR inlet) if you want to keep the 1.2SPI head on.
