Question 531 head - tappet settings

Does anyone have the tappet settings for B230et/ 531 head?
Any info on valve springs vs boost, there at 65 at the moment.
Cheers

Volvo does the clearances as a checking range and a setting range. If I recall correctly the checking range is .013" to .018". For setting it's a bit more narrow. I use .015" to .016" for setting the tappet clearance. Cold engine.
