my ls6 heads have been milled twice, i believe .040 total, and i have no clearence issues. you can always get a little thicker gasket to be safe, but iv'e heard there are some issues if they are too thick. you can put the heads on with some clay on a piston then rotate the motor by hand remove the head and know for sure

There is a post by TSP(post #14) in the following linked thread that states the average measured PTV with the MS4 is .060 on the intake side. Most folks will tell you not to run less than .080 w/o flycutting. Add to that the larger intake valve and you have less than .060.

You want the answer? Mock it up and check it and you'll have your straight answer. Duration will cause ptv contact before lift will.
