I have a feeling what the answer will be. My 440+6 after it's long winter nap is puffing blue smoke out the exhaust. Before putting it away for winter it didn't do this. Only engine work this winter was to have the carbs professionally rebuilt. I've had the car only a few years, so I don't know much service history. I gave it a good run today and the first time I really jumped on it a big puff of blue smoke out the pipes. Is a valve job in order ?????

Drive it more. A good run is 50 or more miles. Heat cycle a couple times. Then have someone follow in another car. Only then think about valve guide seals.
 
do a cylinder leak down test. if that doesn't turn up any issues take a good look at intake manifold sealing.
 
When I had a similar issue, it was only when romping at full warm up and a puff between shifts. It too was blue. The valve guide seals solved the problem. Not an easy job. I had help. The seals used by the builder had been modified/upgraded since the build 6 years earlier. An experienced hand needs to do that job. Keep is posted.
 
I know this is an old post but just came across and had to chime in. I agree with badmopar67, it's probably the seals. Good news is you can do it yourself, even without a compressor. I just did mine. All you need is a spring compressor, light hammer to free the keepers and of course good mopar viton seals. Feed the rope into the spark plug hole and gently turn the crank to push the rope gently on the valves, then you can compress the spring remove the keepers, install new seals. Works great. Good luck. The top of the line mopar seals are under $20.00. I used Mopar P4120492.
