Bullet cams is my choice. The issue you'll have is the wide LSA of a stock cam(which cannot be moved more than 1 degree) will not work if you want best performance. Most NA combos are going to like 106-109lsa's and the 114lsa just won't be very close unless you run really tiny lobes. There are some magnum cams on 111lsa which would be a better choice for a regrind.
