I personally like the specs and the price on the zex/comp cams #57200. I also like crane's 253-0012 cam. But the best cam out on the market for the B series is suposed to be the Buddy Club spec 3. Actually the spec 4s just came out last week, but I haven't heard anything about them yet. Let me look into it....
**Edit** - I checked out buddy club's website and they still only list the spec 3s. I'll keep looking for the spec 4s but I heard they are race only so the spec 3s are probablly what you want anyway.
Description from Modacar -
Buddyclub spec III camshafts best new cam on the market. best overall power band gains of any cam.
This cam creates an ideal power band, with substantial power gains from idle all the way up to red line.
Buddy Club spec III cams are easy to tune and have much better throttle response than OEM cams.
Definitely a versatile cam, accomodating compression ratios from 10.0:1 all the way to 13+. After testing 14 sets of different cams in our project car, we found this cam to be the most impressive...Even though it did not make the most peak Hp, it had the best over all powerband and response!
Dyno gains of 8+ Wheel Horsepower @ 4000 RPM and 10+ Wheel Horsepower @ 8200 rpm. OVER Civic Type R cams. Peak torque also increased from 2-10 ft/lbs across the entire rev range.
This camshafts is ideal for stock bottom end ls/crv VTEC's reving to 8,000-8500. Tuning & technical advice is also available from us after you have purchased these camshafts
