Thomas,
I read your build sheet on your sig. 20/21 cam is still an emissions cam , this should be very close .
The only way to be sure you are making max Hp is to have an active AFR gauge in the car .
The CIS is most likely not providing enough fuel to make real Hp.
The best and easiest way to do this is to make an adjustable fuel pressure regulator and mount it between the seats
the afr numbers you want are 12.8 for power and 15.0 for high speed cruise
This is what I did , but because of our stupid laws i can not recommend or teach you how to do it
