Looking to make primary header pipe length and diameter calculation.

My engine is an '84 completely internally stock.
These are the values I'm seeking, I have some and I'll list them so you can tell me if they're correct:

1. Stroke. 3"?
2. Bore. 4"?
3. Number of Cylinders. 4 obviously!
4. Exhaust valve diameter in inches?
5. Exhaust valve opening point in degrees?
Exhaust Valve Opening Point is given in degrees before bottom dead center (BBDC). Entered values should be greater than 0.
6. Exhaust valve duration?
7. Exhaust valve center line in degrees?
8. Peak power RPM. 2800 rpm?
8. Volumetric Efficiency?

The values I came up with are from http://www.automobile-catal...iero/fiero/1984.html
I will be using the calculator found here

Any help in finding these numbers or the formulas/ procedures to calculating them would be awesome. I know there are some smart cookies out there on the forum. And you can save the Duke trash talk, I've heard it all before

yes, your bore and stroke number are correct. Fortunately, My duke is still in one piece in my car, so I can not give you any of the other numbers, sorry =/

Lol ok I'll save the trash talk, but out of curiosity, what are you attempting to do to your 92hp paper weight? (lol ok. I'll be nice now)

I am actually a bit interested, as after I am done with my Fiero, I am going to have a full '84 drive train, and front and rear suspension left over, just begging to have a tube steel frame build around it and turned into a gokart/buggy/open wheel death trap.
