Any difference in 1.0 and 1275 heads?

Hola. Does anyone know if the two heads are the same? Eg valve size, combustion chamber size/shape and port sizes? May buy 1.0 engine for the pistons end might play with the head a little!!! Cheers peeps

I've got some cup cams in my 1275 head which I would transfer. Thanks fir the advice though. A milder camshaft for more torque low down maybe as small capacity motor 1L.
