Don’t even bother milling the heads only .030” since doing such will only hand you a measly 1/4 point gain in compression.
Go .045” or better yet .060” or put that money that would have gone into a .030” cut to better use elsewhere!
The only thing is with a .045” or .060” cut you will have to cut the intake flange at least .030” to get everything to bolt up happy.
Like anything else these days milling beyond just a clean up cut has gotten expensive.
Also milling beyond.030” will call for shorter length push rods.
Yup, everything starts to snow ball at some point.
