God, i wish I could figure out where all my coolant goes. The dog is still alive so I can't be leaking it, no white smoke, no overheating, and good cyl compression and leakdown test.
Coolant could be going into a cylinder. I just finished changing head gaskets on my 440 because of this.

You need to start your own thread. Trying to follow two questions from two people in a thread is confusing.

I did not ask how much they removed when resurfacing. The heads looked good when coming off, so would not think they took enough off to cause a problem with intake sealing. It's possible some coolant got into exhaust pipes when pulling heads, but the smoke never let up. Everything was free of coolant in cylinders.I did not look for bubbles, but also did not run it very long-probably 2 minutes each time(twice). I guess I'll just order another set of gaskets and try again.I may try for a better intake gasket set which may seal a little better. I've built about 5 318's, but never had a problem with them.
I would do the following:
Don't pull the heads just yet
Fix your intake(s) leak, and be very careful with your gaskets, and make sure everything is clean.
Pull the plugs and inspect to see if you can determine which hole(s) are affected.
Run the engine up to temperature, and if theres no identifiable leaks you can find--other than exhaust steam,--then pull the plugs again and look for suspects.
I'd bet your intake leak is the start of the problem.

Years ago I put a low miles junkyard 340 in my 70 RR ( the FIRST gas crises) I ran that thing a week or more before it stopped burning oil. It had less than 20,000 miles on the wreck (I saw the car). I even ended up complaining to the wrecker. He assured me it would be OK and that they'd stand behind it. I put over 80,0000 more miles on the engine, before it got torn down and went into the old FJ40
