9.5mm lift is the absolute maximum you can use before fairly extensive head modification is required.
The cam lobe will hit the head casting at 10mm it is very close with 9.5mm lift.
Different valve springs will also be required at higher lifts too as the original springs will go close to "coil bound" much above 9mm.
So drop in cams, i.e only timing and shims needed are limited to lift of around 8.5mm, duration should not be too much of a problem.
If I were doing it all again I would look for cams with around 8.5mm lift and a duration between 256 and 268 degrees depending on compression ratio, effectively a higher compression (10.5 - 11-1) can make best use of the longer duration. hth
