Nah, get Your money's worth out of it!!
Locking cam & crank in place while tightening was probably facilitated by purpose made tools & practice, but they claimed it gave them flexibility, and saved a bunch of time.
All the Ford DOHC Z-tech etc. engines use no dowels or keys on the cams, they use an alignment bar that slides into slots cut into the tail end of each cam, and a screw/pin to lock the crank.
