YES ... it is not a good match in there.
Cam is probably to small, (what is its size @.050"...?), for the intake, compression is to low for the heads and the 750 carb is way to small for nitrous.
Given those mismatches there are many ways to go about correcting it however, it will depend upon the vehicle and how it is going to be used as to which is the best way.
What's it weigh...?
What is the rear gear...?
Auto, (torque converter), or stick, (Flywheel), ... ?
What tire size is going to mostly be used...?
