I also expect that timing is not correct. These timing chains have a small pitch, so it's easier to get it off by one notch than on the diesels with the larger pitched chains.

If the cam timing is retarded, then you did not bend valves, if it is advanced, you probably did, and that is why you are seeing the compression variation.

I think you should pull the upper timing cover and ensure that your timing is correct. Also, did you reset your ratcheting tensioner?

Good luck,
