SC Cams will take you to 6000 RPM with no problem and 964's give more top end at the cost of some low end driveability. The k27 turbos will run out of breath before then anyway. Generally, the K27 flow takes you to about 5500. I wouldn't go beyond 6000 with the stock rod bolts and the mods you mention. Skip the boattailing, knife-edging, cylinder reliefs. Headers, turbo(K27 7200 or 7002) and SC cams will do wonders for these engines. More flow? Go with the 964 cams and a Garrett GT35r.....but then there's custom header flange and turbo to IC interconnect tubes in the works.
