<VV> Shimming of Heads

[airvair]

The factory used a special .010" thicker barrel spacer under the jugs of 
the 140/auto/air engines. Perhaps you could use something similar.

If it were me in that situation, I'd go farther and have the heads 
milled down to the quench area, which is known as "removing the step" in 
the heads. Using a standard head gasket, this reportedly optomizes the 
quench area, which not only negates the effects of the increase in 
compression, but is supposed to make it possible to run on regular gas.
