Hi everyone
Any help or suggestions would be very much appreciated.

This is actually an extension of my last post.
Just finished putting this car back together last night.
I was going to drive to the gas station and be done with this,,,but
The car started and ran beautiful. I shut it off, and when I restarted it it stumbled like it was missing. when I put it in reverse the rpms would drop and stall. If I play with the gas pedal it will smooth out around 750 rpm, and seem to run normal.
We have 3 cars and mine is the only one running.
I am getting to the point of just setting it on fire.
Below is a list of what I have done:

carb rebuilt, cap rotor and wires.
cam seal
thermostat
The keyway broke on the cam sprocket and turned just enough to bend all the exhaust valves.
New valves
Had a machine shop check for cracks
Head Gasket set....
water pump and timing belt
new alt and belt
Replace the high pressure line
rear wheel cyl
4 tires
