We all know the T1 SPS cams work great on both sides. The 748R exhaust is higher lift than the T1, but not as nearly as extreme as the 748R intake. Duration is also 20 degrees longer than the T1 exhaust, but substantially shorter than some other desmoquattro options. I am not a tuner and can't give you absolutes, but I think with the right timing these should work quite well. Not sure how the significantly smaller 748 valves (compared to 996) will affect flow, but somebody will be able to advise you on that, as well as timing.
