Content-Type: text/plain; charset="iso-8859-1"
I've seen this tech bulletin, but I'm not sure what you mean when you say
"blow off the barrel spacers." The heads on this engine are AMC heads so I
can't eliminate the "aluminum seal 021 101 341A between cylinder and
cylinder head" and the bulletin specified substituting 1.6mm (.063") barrel
spacers ("aluminum shim 071 101 341") in place of the paper.
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.
