Compression Testing ....(Hot vs Cold)?

Hello,

My 289 was rebuilt 4 summers ago now and I'm not sure if my rings are still seating.

The reason I say this is there is a difference in the hot vs cold readings.
Basically the "cold" readings are:
151,149,136,148,155,150,140,133

The "hot" readings are:
160,160,160,165,152,155,155,150.

Is there supposed to be that much of adifference between the hot and cold readings?

Also, when i squirt oil in the cylinders some of the jump up to 170 and 175.

Does this tell me anything about my rings and if they are seated properly?

Thanks, Greg.
