Smaller brake booster?

[67cam]

I am wondering if I could get a 1980's style brake booster and master cylinder to work on my 1967 disc brakes for my camaro. The booster seems to be much smaller then the original. Wouldn't that make it build pressue faster and brake better? Or would it build less pressure and not break as good. I have put in a big block and the tall valve covers are not fitting and I am trying to find more alternatives to cuting the bottom corner of the cover. Anything would help thanks.

The smaller dual diaphragm are more effecient also and might even have too much assist for the pedal ratio.
