[KTL]

Stock SC/Carrera overlap/lobe separation is 113 deg. Your cams you're looking at have 101 deg. The 911S cams have 98 deg. Point being, is you're a lot closer to an S cam than you are stock. S engines are known to be a bit lacking in low end grunt but really come on strong when you get up in the revs. I believe the S redlined at 7300?

Timing card from Web Cam also indicates a fairly high lift spec at TDC overlap of 4.2-4.4mm. Stock cam is 1.1mm I believe? Not saying that cam won't work, as your pistons have sizeable valve reliefs in them.

As far as the rod bolts, for your intended use the factory rod bolts are suitable.
