I'm going to install .020" barrel spacers in place of the .030" ones that
are there.  Since I cc'd the heads and measured the deck height prior to
putting the engine together I know what the CR is and what it will be.

Latest word not in Muir, Bentley, Tom Wilson is that it is good to have
an aluminum spacer as a heat transfer devise. The thickness doesn't
matter that much as long as you come out with the deck heigth that you
want. If it takes leaving the barrel shim out it is just suggested that
you seal it with something like Permatex Copper sealer.
I've never reused VW OEM heads but I see that variable instructions exist
for compensating for recesses pressed into the softer VW heads by the
cylinders if they are not fly cut back to the proper depth. Which of
course has no bearing since you've got AMCs.
Sounds like you've done the math ................. You can double check
it at.
