I had the same problem with my bridge,some questions helped me solve it.
I`am going to ask some questions,please answer all of them,so we can help you solve this
Let me ask the obvious:
1How old is your battery?
2Is it properly charged before attempting to start it?
3Is it a large/factory sized battery,or a small one?
4What plugs do you have in?
5Are all the plugs even coloured?Or is the front/rear rotor darker or lighter?
6Did you replace all the hard seals in the locations they came out of?

1.) not a very old battery, still putting out good voltage.
2.) charged overnight before starts. (sometimes charger is set to 75v starting setting while cranking)
3.) large factory sized battery.
4.) just put in new NGK's
5.) the plugs are all a healthy grey color (unless i flood it...then they are kinda wet...but still a greyish)
6.)
this is where i may have gone wrong. during the teardown process i got things a bit mixed up, but the seals seemed to fit well in the places i put them back into. also, these *are* different rotor housings than the rest of the engine parts, because the other ones had pretty good signs of wear on the edges.

the apex seals were relatively easy to move in the grooves. i doubt they are sticking. i *could* see the seals with mirrors in the spark plug holes, they dont look to be sticking.
i let the car run for just over an hour last night, and im gonna go let it run for another hour after school today, then check my compression to see if its gone up at all.

NEW COMPRESSION RESULTS:
my last compression numbers were when the car was cold, this time i decided to test the compression when the car was warm (like you are supposed to) and got the following results:
FRONT ROTOR - 35psi
REAR ROTOR - 25psi
will driving the car help at all? is my engine a lost cause?

It's too bad that you will have to re-open your engine again, but at least it is salvageable. Good luck with it man....
