Exhaust theory

I'm rebuilding a motor for my '74. I will need a new exhaust system soon and was wondering about sizing. I am building a stock set of heads right now to use with the stock intake for autocross, plus I'm planning on building my spare set with bigger valves and opened up porting, and adding a 2 barrel intake for whenever I want to up the performance. My question is this: will the 1.75" MSS exhaust be good with the stock setup, or does the system need more back pressure to maintain correct dynamics? I know that it makes a big difference on 2 strokes, but am thinking it is less critical on 4s.
Thanks, R. Wellman
