To find the correct shim size, you have to actually be building the thing 
yourself.  I found the correct size whaen I had the P&C's on.  You have to 
measure the deck height, the head's combustion chamber volume and calculate 
the volume which the piston will sweep.  You can't anticipate the correct 
shim size, because of all the variables which are involved.

As to the right C.R.- You'll get as many answers as there are people to ask. :-)

Hope this helps.
