Default TFS 215s: How Much to Mill?
My LS1 has an SNS TorqueMax Stage 2 cam: (227*/235*; 0.618"/0.605"; 110*+3*). I'm considering TFS 215 heads. Does anyone have an idea of how much I could mill these and still maintain adequate PTV clearance?

If you're considering milling brand new heads, then you're buying the wrong head.

Orders ones that already have the chamber size you want.

I've seen that TFS 215s can be ordered with combustion chambers of various sizes, but I assumed that the vendors just mill to reach those. Are you saying otherwise? Or that I should look into entirely different heads?

The only way to know for sure is to check PTV, see what you have then decided after that.

TFS genx 215 are a 13.5* valve angle... it helps alot with PTV clearance... with that said.... always....ALWAYS measure PTV with aftermarket stuff.
