Bob, i agree, do not use this cam.
Call Comp. Cams tech line & they have tremendous list of profiles that they will custom grind for your engine.
Check out their xtreme energy list of profiles in the 275-278 degree area with lift in the .525" area if you have the clearance allows. Check out this link. The grind is #5445.

Since the exhaust flows so well i would go with a single pattern profile with 109 L/C.
They normally grind their cams with 4 degrees advance. However you can make that choice.
If you are concerned about wear they can nitride harden the cam from 52 rockwell C hardness to around 60.
Looks like Clay Smith Cams stamped the wrong info on their cam. I would not recommend their grinds for your engine. The only decent cam they offer for a 200 or a mild 250 would be their 264-214@.050"
