Hood scoop cracking prevention ?

I have panel bonded (jb weld panel bond) and bolted (16 bolts) my six pack hood scoop on my 73 scamp. I have read many many threads on cracking. Many say that it is inevitable. Yet I cannot find a single picture of the cracks. Where exactly does it crack? At the junction of metal to glass, in the middle of the blend? Or everywhere along the blend? I am asking because I am contemplating squaring off the metal to fiberglass junction so that any crack would be at the junction and “invisible” in the seam. I will be sanding the area square today and prime it to see how it looks. My thoughts are that it will be something different. A six pack scoop mounted more similar to a hemi scoop than blended like a six pack. Any thoughts, pics and advice?? I will start sanding in a few hours.
