I see what your saying. I'm just looking for the simplest way to set them with adjustable rockerarms. I got it now though. Since I'm currently doing it I set one to just no end play and gave it a half turn. Then I turned it just until the valve started to open and guess what it was 1/2 turn as well. So now I know for sure that at TDC Compression set it to zero lash and back it off 1/2 turn and it will be a true adjustment throughout the valvetrain for normal lifters!:cheers:
