72 360 first start question

Actually when I have done rockover I have had the intake off & I go by the lifters themselves (not that I recommend that you go back in there). I dont have the final word on the compressed or uncompressed (from the oil) & I hope others can chime in on that. yes you want em both moving & go back & forth on the dampener bolt till the height is the same. actually I'd start with the slit at TDC & see how close that gets you for a start then work the height/movement
