What cams for 2,7?

Hi
I ve a 911 1974 2.7 with the same problems or maybe more than norm! Now I've bought the 2.7 1973 rs cylinders and I want to put the best cam I can, always thinking of having more power. So my doubt is between CIS s cams or CIS SC profile cams. I've also seen there's a possibility of putting 964 cams?
Then my final question would be... What would you do?

The 911RS pistons are cut to be used with the RS cams (which are the same as the 911S cams), so you won't get what your looking for with the CIS system. At this point you probably want to go with a good set of Weber carbs, and then also use the 'S' cams, or maybe something even a little bit more aggressive than that.

And those would be the original, MFI "S cams", not the CIS S cams he was thinking of.
