If I was forced to pick one it would be the 252h but really a custom one is not much more and the difference would be noticable.

If I was picking from a catalouge it would be this hughes cam

The extra lift hughes gives you will help keep it from choking as the RPM climbs before a shift as long as you get their recomended valve springs.

If I was ordering one from scratch I would get the hughes cam I listed, have them change the ex lobe to be the same as the intake one. That will reduce overlap and that will reduce unburned fuel going out the exhaust as well as give a couple more degrees to push on the crank before the ex valve opens.
