The other would be seating the rings. Either on a dyno if in car then maybe get brake pressure as high as you can and run motor in gear as high as you can. If unable to hold in 1st gear try second gear. I had trans brake on my super stocker and it worked well on rebuild. Don't forget to remove rpm chip. Hopefully carb is not leaking when sitting and washing out cylinders.

Good morning to all,
I was catching up here this morning and that suggestion is a good catch. I was about to say if the engine is broken in properly, that the problem could be "deeper" meaning you'll have to scrutinize all the parts much more closely. I did have a problem recently where the way the Mfg. cut the Second ring stack, the cutter let a burr on the back side of the ring - causing it to stick in the ring land. The engine wouldn't seal and did smoke. I'm not saying this is your problem, but I'm stating that going over all the piece's in the " system" need to be inspected. Had another situation with rings where they " micro welded " themselves in the top ring land causing the top ring to not seal. I'm bring up examples so you can take your engine apart and " inspect " each part. Without the parts in front of me its a little difficult to see for myself.
Keep looking - I'm sure you'll see the problem.

Respectfully,
