you gotta also factor in the 89mm ls crank stroke.

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by hybridlsR &raquo;</TD></TR><TR><TD CLASS="quote">arent the usdm itr pistons 10:6? with a higher comp headgasket another .2 to .3. so id guess 10:8 to 10:9 comp </TD></TR></TABLE>
10.6 is the pistons in an itr
you did not facter the +.2 from the gsr head and the +.2 from the 89mm crank

its going to be 11.0 with a stock head gasket
so it will probably be 11.1-11.2
