0.045 is the answer and yes, Milling them beyond 0.045 is not recommended. Hurts the flow in the chamber. Also with such a large intake valve, it's hard to throw duration at a cam without flycutting.

100thou, no porting, stock manifold (L76 manifold) still fit and lined up. made big hp with factory ls2 cam and e85. 11.3 in 3700 lb car at 122mph. fly-cut pistons, but actually could get away with it.
