Yes, you can't go 'much' more aggressive on the cams than 964 if you stick with CIS because of the reversion issues.
A couple of mates have rebuilt 3.0 engines with different cams (they both twin plugged theirs), both still with CIS and the power ceiling for 3.0 engines on CIS seems to be about 235bhp.
Another mate went Jenvey ITB's and EFI on his 3.0 and he's putting out 285bhp (IIRC)
Ditching CIS allows you to run much more aggressive cams and removes that ~235bhp ceiling.
