The good news is that those stud-adapters can be removed, and the pedestals properly machined.
The picture of the kit that Doug posted would make me think twice about using them - just my $.02.

I am not here to rain on anyone else's parade.
Crane created those studs as a solution to a specific problem of how to simply add adjustable rocker arms to the heads without removing the heads and machining the pedestals down and retaping them for 7/16" studs.
Consider what you are looking at, Marlins remarks and the fact that even with 7/16" studs many have found that even more strength was required in the valve train in the form of stud girdles.
The stud girdle ties all the studs together to act as a single entity in order to reduce flexing of the studs and thus stud fatigue and shearing at the base.
It is my opinion that the Crane kit will in fact work if the stresses do not exceed those of the ORIGINAL valve train.
That means original valve springs, original camshaft, original 5,800 rpm limit.
If those heads are off the engine (and that's what the pictures would indicate) remove the kit, machine the heads to the Ford specifications, install new ARP 7/16" x 7/16" studs.
Drop them off here. I'll do them for you. Ain't no BFD and I'm not a machine shop. Wait...no, don't bring them here, go to your local shop. Those things are too heavy to be humpin' around. I went 'luminum!
