Go back a see which item is bad before you look at something that was there when it ran good. Bad coil. wrong coil, mis gapped plug cracked cap. wires not seated or damaged while changing all this, any of that could cause a miss but not usually a exhaust manifold

Thanks for the replys.
This is what is really throwing me...I figured something I put on was bad so I went and changed everything back to what was on there before (except the fuel filter). And it still runs bad. I rechecked the timing and dwell-- both are good. Dwell is about 31 degree and timing is about 12 degrees. That is when I noticed the crack in the manifold.
I don't have a good idea of how the intake and exhaust and carb are all connected, so I was thinking the crack may be causing some type of vacuum leak?
The engine ran so good for a day and then this happened -- I was hoping it was something simple.
