Indy/RHS X HEADS GASKET UPDATE

I wouldn't mill the intake or it'll be a 1 off piece for that motor only.
Mill the intake face of the heads cause thats what will be screwed up after milling the deck .020 or so thou.
Not that in some cases in isn't a good idea, but I would say thats when the heads are already bolted on and you cant afford the time/head gaskets.jmo
