Leak down Test and Replacing Rings

[Donald Gallimore <dongallimore@xxxxxxx>]

Partially ran a leak down and compression test on a my 440 yesterday. Engine was 
not warm, just room temperature of about 60 degrees.(Does that matter?) 
 Compression on 4 cylinders (1,3,5,7)  was around 180 psi (9.5-1 engine) but 
rapidly fell off once I stopped turning the engine. Leak down was 85% for 
cylinder 1 and about 45% on 8, 4 & 3. (Had to quit for dinner while trying to do 
#6 which is tough to do due to clearances)  Based on the sound, the air is 
leaking past the rings, not the valves. Since 1 and 3 were tested both ways, not 
thinking head gasket.

So, I think I need to rering the engine. 

If I need to rering, can I hone the engine while it's in the car with the crank 
in place or is there too much grit generated and I'm pushing it. Can I reuse the 
rings?  I suspect the problem is a result of gas washing the oil off the walls 
since I've had a few heavy fuel discharges from the carb - stuck floats due to 
my fault of putting the carb together incorrectly
