my mate did exactly the same a couple of years ago, and if i remember rightly it made a fair difference in power. only a couple of weeks after the bottom end blew up. the garage said it was due to the 1.4 head.

who knows.........................

will work aslong as its spi unless your converting to mpi.
no improvement in power though iirc the combustion chambers are bigger so you will have a lower compression ratio

1.2 and 1.4 spi heads are identical, bar the larger chamber as said.

SRi is a very good head, but your inlet wont match it.
