Trying to input the information into an engine simulation program that I have. This program is pretty damn accurate at estimating HP and torque, as well as fuel usage and just about everything else involved in making high HP.

Won't help you at all.
Flow numbers for a D16 SOHC (D16Z6 etc...) arenon congruent numbers. Ie, the flow of the head doesn't match the flow of the REST of the inlet system. Most of the flow numbers you'll find are from "old timers" with flow benches that flowed the heads without the intake and throttle bodies, as well as intake runners. Without those things included, you'll find that your D16 flows about as much as a Briggs & Stratton. I've found flow benches TOTALY useless.
As a matter of fact, one of my WORST flowing on-the-bench heads made more power than any design I've tried. Now it's one of my staples.
So, will the numbersyou'r trying to find help you at all in your program?? No.
