quick compression ratio question

["brian clarkson" <brian107@hotmail.com>]

Hey list, 
I got my case back from my machinist yesterday. This engine was rebuilt 
by  myself about 6 months ago, and started up about 6 or 7 times before 
it locked up.  I dropped it out, tore it apart, and brought it to a 
local builder (a different guy than I had do the machine work the first 
time).  He told me that my crank was ground way out of specs, that the 
align bore was incorrect, and that the thrust surface was cut wrong.  I 
had him do all the machine work and paid him to put the case back 
together (just less headache for me).  Now I have my case back and am 
preparing to build the rest of the bottom end.  My question is this:  
What compression ratio should I be looking for?  I cc'ed the heads, 
measured the deck height, and found the fixed volume of the cylinder as 
per one of Bob Hoover's sermon's recommendation, and found my 
compression ratio to be approximately 8.4:1.  This is a re-rebuild, so I 
want to get it right this time.  Any recommendations? I'm not at the 
point of no return just yet for the installation of shims (I'm thinking 
of about a .060" to lower the ratio to 7.4:1.0.
Thanks, 
Bryan
