Question Question about stock cam specs

I am wondering if anyone has or knows where I can find any info regarding stock cam specs for 87-90 GTs. I know that a few minor changes were made during those years. Ford Racing's website lists the following as "stock specs" for 5.0L HO cams.

Advertised specs are 266 Degrees/266 Degrees duration, 0.444" lift. Does anyone know if this is close?

Also, what is the max lift you can run "safely" with stock heads and stock 4 relief pistons?
