Depends which 1.2 head you're comparing it to, 1.2 and 1.3 carb are the same, 1.2i is plain crap. the 1.3 cam has slightly more inlet lift than the 1.2 version.

its the carb version!
so how much differance would it make if i put the 1.2 cam shaft onto the 1.3 ports!or should i just hold on and get the 1.3 csm shaft to go with it

the 1.3 head might actually lose you power since its CR might not be the same.. also the 1.2 carb head had better flow as std compared to the 1.3 version...

Leave the 1.2 head on.
Fit a 1.4SR camshaft for greatest gain from a std cam.

When fitting a GTE/GSi cam to something like a 1.2i, the gain is about 6-8bhp.
So you should get about 5ish with a 1.3 cam.

Long Live The Nova is correct, the 1.4 cam is better. It has the highest lift out off all the std cams and the best duration, have a look at the cam specs in the haynes manual.

Doesn't have to be out of an sr either, just any 1.4

As long as the 1.4 aint a MPI or SPI engine. ;)
