Milling heads 0.060 will certainly require the intake faces to be milled. Check prices before you do this, it won't be cheap unless you live in a parallel universe. Two heads and two intake faces equal 4 setups and 60 is a lot to take off, will require several passes. I was quoted $200 years ago for flattening out the heads, meaning not milling that much. Anyone got current prices for the work?
