head milling

You don't need to thank me, those numbers came straight out of the Chrysler Racing manuals. I've milled 340 J heads and 273 heads (920 casting #) and their numbers are spot on, including chamber cc's. In my experience, the bottom of the intake does not come close to the block. I usually only mill heads .040 to reach minimum NHRA chamber cc's. Except /6 heads which are stand alone so there is no relationship to worry about.

We'll agree to disagree. Your comment made me think about the actual geometry happening and caused me to model the problem and visualize what was going on. So, yeah, thanks for pointing me in that direction.

For a long time I went by the idea that milling the heads required milling the intake. Will that work, of course, but simply milling the heads on both surfaces eliminates the need for milling every manifold that gets mated to those heads from then on. Way simpler to do it the way you mentioned.

So, just to be annoying, I'll say it again.

Thanks.
