Help with Valvesprings and valve float. Noob

Little back story about the engine build in the article I linked.......
One of my friends/customers was exchanging emails with Dulcich about that build prior to the motor being done or on the dyno.
He told me what the plan was for the cam and rocker ratio, and I told my friend it wouldn’t work.
BB with 1.7 rockers....... same as all BB Chevies, Fords, Cleveland fords.
None of those platforms respond well to fast rate hyd cams if you need to turn any rpm.
I had worked through all of that 10 years or so before that article ever came out.
