I think you will be happy with the kelfords or the S2's. Both are great cams, I debated on the kelfords, but I wanted more top end as that is what my setup was aimed at, however I didn't seem to lose any low end
Kelfords are proven and work great, AMS still uses them in all their builds I believe. The kelford B's are designed for 35r sized turbos, I asked kelford and that is what they told me, so you should be good.
