Question: Did you ever do a compression check in the past with this new engine? Do you know if it ever had good compression in all cylinders? Maybe the rings never seated in it? I would do what the other say and run it hard a few times -- full acceleration and lots of RPM changes and see if the compression gets better. If that doesn't work (and the valves are seating/sealing well), then you might need to pull it down, have the cylinders honed and put new rings in it -- and then run it hard to ensure that seat well.

Good luck!
