I recently bought this vehicle as a non runner. I pulled it apart and found the cam chain tensioner had failed and valves bent. I had a machine shop rebuild and surface the heads. It has 150K miles on it. I put it back together and now I get a P0306 code. It runs but a bit rough. I swapped cylinder 6 and 4 coils and it did not follow. I replaced the plug and the injector and it has not made a difference. Compression I get cylinder 1,3,5 155 cylinder 2,4 165 and Cylinder 6 175.

Would the difference in compression cause the misfire? Other suggestions?
