wound up being a major PITA to make right. Removing the booster made the car difficult to stage even for Doug so I've spent the last couple of days "re-engineering" the stock pedal assy. The OEM assy. is quite complicated so I went to my favorite place (junkyard) and got another Cavalier assy. and an 80s Camaro assy. and "blended" the two together. I now have a 6-1 pedal ratio (OEM was between 3+ 4-1) and a nice feeling brake pedal.
My plans for this week are to build a couple of different collectors and see if I can make the header work a bit better.

What front tires are those? Are they Circuit Racing Slicks?

I would guess that they are some sort of an asphalt "circuit" slick. Hoosier 19.5x7-13.

Well, in the openness of "fair-and-honest" reporting I guess that I should mention our last outing at Cecil. I don't really WANT to as it wasn't a banner day but I guess that it could have been worse. I at least learned some stuff.
The brakes worked out great! Doug could hold the car at 3 grand if he wanted to.
I built 2 different collectors for the car. The original one was 2 3/4" dia and about 15" long. I built one 2 1/4" and 15" and a second 2" and 24" planning on cutting it down.
I don't have my timeslips and notes with me but we made 7 runs all between a 15.25 and 15.28. Not too bad for changing things between runs. It wasn't a very good day, low baro., high humidity and head wind but at least the sun was shining. As I changed the collectors, we started to see a pattern develop. It went it's best MPH (by 1 full MPH!) with the 2" collector cut to about 10" long but it went it's best ET (15.25) with the original collector.
This past week, I was able to find some specs on the original cams and although they're both very small, the exhaust cam is really small. I'm starting to think that the restriction that is cast into the original exhaust manifold is there for a reason (duh, gee do ya think?). At any rate, Comp DOES make a "streetable" cam set that is a bunch bigger than the original ones and is under my .430 lift limit. I guess that I've got to buy some cams.

Billy,
Since it is DOHC. Have you thought about playing with the phasing of each cam before you try new cams? Unlike a single cam setup you can change LSA / overlap.

Yes, I have and the exhaust lobe is seriously retarded. If there wasn't anything commercially available, I would have "played" with moving the existing cam c/ls around. It does need (at least) a larger exhaust lobe.

Billy,
Thanks. Maybe I have confused this with one of your other threads. I was thinking this was as low a $$$$$'s build as possible.
