A crows foot will change the ft-lbs (or in-lbs) by a tad depending on how it's oriented. Really not that big of a deal as long as the wrench and crows foot is in the same orientation for all of them.
That being said, I've rebuilt enough motors to know by feel what the proper torque is. believe me, it's takes some trial and ERROR!! haha. It sucks when you have everything almost together and then bam, last bolt breaks. I now have a magic touch!!
As long as you're in the general range for torque, what really is more important than the actual ft-lb spec or whatever is that they're all torqued down EVENLY (meaning in the cross pattern) and to the SAME torque. The actual number, eh, whatever, as long as it's at or greater and in the general range, you're good. The even and same torque is the most important part.
