i had a valve job done on my d16z6 head, before the compression numbers were 80, 120, 110, 120, he only repaired the ones that didnt hold compression which was the 80 and 110, now i installed it and the numbers changed to 120,180,180,150, i dont understand that, i did nothing to the bottom end. could my crank and cam be off a little and cause these numbers, i figured they would all be around 120 at best, any suggestions?
