I've heard anything from 8 thousandths to 13 thousandths.. Seems like I heard 10 is the max though.

I had 10 thousandths taken off my 6L heads and they worked flawlessly. fwiw

Find the member...Gearhead2012, on the .org. He's an encyclopedia of information on heads, especially 6.0's.

For your light reading...lol

General rule of thumb was always max of .008" last I knew, I was always told if it was more than that, scrap the heads. Real reading is the 3.74" min thickness. Once you take a bunch off there is more to it than just decking the head. Recessing the valves, shimming the springs etc...
